NASHVILLE -- Tennessee quarterback Jake Locker is out with a hip injury, and coach Mike Munchak doesnt know for how long. Luka Doncic Jersey . One thing is certain. It couldnt have come at a worse time for the Titans or Locker. The coach said Monday that Locker will have another MRI exam Tuesday to diagnose the extent of the injury he suffered Sunday against the New York Jets. The test will give the Titans a better idea of when he can return. Tennessee (3-1) is off to a surprising start after going 6-10 last year behind Locker, who is playing the best football of his career. Munchak remained optimistic Locker will be back this season and said any reports on how much time Locker will miss is simply guessing now because the Titans havent discussed the possibilities with the quarterback yet. "He still has swelling so they dont want to speculate on terming what that means or how long and rehab and how long this all will take," Munchak said. "Hell be MRId again tomorrow, then well have a better idea exactly what the time frame before he can actually play or get back on the field." Munchak said Locker also sprained his right knee on the hit. Ryan Fitzpatrick now will replace Locker in Sundays game against Kansas City (4-0). The coach did not rule out a fracture or dislocation until after the next tests. Munchak dismissed reports earlier Monday that Locker will miss at least a month, saying that determining the severity of an injury can be difficult early. He also said the Titans will announce how long Locker is out after Tuesdays tests. "Then well have to make some decisions and see exactly where were at," Munchak said. The Titans signed Fitzpatrick in March to a two-year deal, and right now hes the only other quarterback on the roster. Rusty Smith, a four-year veteran, currently is on the practice squad. Smith said he hadnt been approached yet about being promoted to the roster or heard if the Titans might sign someone else to back up Fitzpatrick. Locker spent the night in the hospital after being injured early in the third quarter of a 38-13 win over the Jets. Locker was hit first by Muhammad Wilkerson and pinballed off Quinton Coples before grabbing at his hip as he went to the ground. Munchak said Locker couldnt pull out his foot with his hip caught in a kind of whiplash effect. Munchak talked with NFL officials Monday about the hits. "The first one was he dropped his helmet into him and unloaded on him, which youre supposed to pull back when youre late. The second one was totally unnecessary," Munchak said. Locker was released from the hospital Monday morning and had treatment at the Titans headquarters before going home. "I want to thank everyone for their thoughts and prayers over the last 24 hours," Locker said in a statement released by the team. "I am going to work as hard as I can to get back as soon as I can. I believe in this team and will do whatever I can to help us win in the meantime." He missed five games last season because of an injured left shoulder. The timing of this injury is much worse. Locker currently is the third-ranked quarterback in the AFC by passer rating behind Denvers Peyton Manning and Philip Rivers of San Diego. Locker currently has a 99 passer rating and is completing a career-high 62.2 per cent of his passes with six touchdowns and no interceptions. The Titans (3-1) are off to a strong start after going 6-10 last season. They wrap up a three-game home stand against the Chiefs on Sunday before visiting Seattle (4-0) on Oct. 13. They host San Francisco (2-2) before their bye in a stretch that looked challenging even before Locker was injured. If Locker missed only a month, he would be on target to return Nov. 3 when Tennessee visits St. Louis. Fitzpatrick helped Buffalo start 5-2 in 2011 and signed a big extension with the Bills. But he went 1-8 down the stretch and was 6-10 last season before Buffalo released him on the opening day of free agency in March after a coaching change. Now the veteran with 81 interceptions in eight previous seasons takes over an offence that has not turned the ball over even once through the first four games, something only the 1995 St. Louis Rams have done in the Super Bowl era. "Weve already made that point clear to him that we need to keep the record going," Munchak said. "Its all on him and his shoulders to come in and be good with the football." Notes: The Titans hope RB Shonn Greene, who has missed three games with an injured right knee, and DT Sammie Hill (right ankle) can do some individual drills this week. WR Kenny Britt, who sat out against the Jets with a cracked rib and sore neck, is expected to practice Wednesday. Steve Nash Mavericks Jersey . Early in the first period, Stuart pinched in from the blue line, hit Nash and was assessed a minor penalty for elbowing. Nash remained in the game for the rest of the first period, but did not return for the second. Jason Kidd Mavericks Jersey . With Bernard hurt, the second-round pick has emerged.Hill ran for 152 yards during a 27-10 win at New Orleans on Sunday, his second big game. He also ran for 154 yards against Jacksonville earlier this season. http://www.mavericksteamofficial.info/jose-juan-barea-mavericks-jersey/ . With one penalty, Fourcade finished in 24 minutes, 58.2 seconds, just nine-tenths of a second ahead of Timofey Lapshin, who shot clean in the cold.GREEN BAY, Wis. - Randall Cobb keeps finding the end zone for the Green Bay Packers. Soon enough, it could lead to a big payday.The fourth-year receiver is in the last season of his rookie contract after being drafted in 2011. He loves Green Bay and shows no letup in proving he can be a playmaker catching passes from Aaron Rodgers.Cobb, who has nine touchdowns in eight games to lead NFL receivers, said he doesnt think about his contract status. The Packers dont seem too worried, either.I guess well have to wait and see, Cobb said Thursday when asked whether he was setting himself up nicely for a future deal.A few lockers away, fellow receiver Jordy Nelson let out a hearty laugh.Nelson signed a $39 million, four-year extension on the first day of training camp in July. He has been worth every penny so far, with 50 catches for 737 yards and six touchdowns as Rodgers top target in Green Bays up-tempo attack.Cobb has been nearly as productive with 40 catches and 578 yards. Always a threat in space, Cobb has also developed a knack for making plays in tight quarters in the red zone.Rodgers said its all about finding the right matchups.Jordy and Randall have had a lot of targets go their way. Theyve been open a lot, Rodgers said. Weve kind of manipulated some formations to try to get them in the ... first or second spot as far as the progression goes.Cobb was especially hard on himself after Green Bays 19-7 loss on Sept. 21 at Detroit, which dropped the Packers to 1-2. He was held without a score on three catches for 29 yards.He has been a regular in the end zone ever since, with six touchdowns in the last five games. He has 26 catches for 452 yards during that five-game stretch.He brings that blue-collar, workmanlike attitude when he goes out on the practice field and tries to make the most out of each and every opportunity, receivers coach Edgar Bennett said. Dwight Powell Jersey. . The thing I really love about him also is the fact that good is not enough. He wants to be great, and he works at it.Especially against Sundays opponent, the Chicago Bears. In his last three games against Green Bays division rival, Cobb has 15 catches for 283 yards and four touchdowns.Cobb had seven grabs for 113 yards and two scores in a 38-17 win over the Bears in September. In the 2013 regular-season finale in Chicago, Cobb had two scoring receptions, including a memorable 48-yarder from Rodgers on fourth down with 38 seconds left to help Green Bay win 33-28 and take the NFC North title.I dont know if we play at a higher level, but we have been more efficient here as of late against the Bears, Cobb said.But otherwise, no extra motivation against them — or at least thats what Cobb is letting on.I mean, its another game for me, Cobb said. I just continue to try to play the best I can to help this team out any way I can.Keep up the production and the Packers figure to be rewarding Cobb handsomely.NOTES: Starting guards Josh Sitton (toe) and T.J. Lang (ankle) missed practice again, though coach Mike McCarthy said he would feel very comfortable playing both veterans without practice time. Lang said he had some ligament and muscle damage, which made the injury more than a typical sprained left ankle. Thats obviously something you have to think about, is weigh the options and not getting better for the rest of the season and be kind of that 60-70 per cent, whatever it is, or just waiting a couple of weeks and being 80-90 per cent, Lang said. Thatd be my biggest fear is having a setback and missing a couple more weeks.__AP NFL website: www.pro32.ap.org and http://twitter.com/AP_NFL___Follow Genaro Armas at http://twitter.com/GArmasAP ' ' '
