NFL-National Football League roundup

Dec 21 (The Sports Xchange) - Arizona Cardinals safety Tyrann Mathieu has a torn ACL and will miss the remainder of the season, head coach Bruce Arians confirmed. Mathieu suffered the injury in the fourth quarter of Sunday's 40-17 victory over the Philadelphia Eagles that moved the Cardinals to 12-2 for the season as they clinched the NFC West title. Mathieu intercepted a Sam Bradford pass and limped off the field. - - - Houston Texans quarterback T.J. Yates suffered a torn ACL in his left knee and is out for the season, coach Bill O'Brien confirmed. Yates was replaced in Sunday's game by third-string quarterback Brandon Weeden. O'Brien also said quarterback Brian Hoyer is still in the concussion protocol and the Texans signed quarterback/receiver B.J. Daniels off of the Seattle Seahawks' practice squad. - - - Tennessee Titans quarterback Marcus Mariota suffered an MCL sprain to his right knee in last Sunday's loss to the New England Patriots and will miss Sunday's game against the Houston Texans. Titans coach Mike Mularkey said it has not been decided if Mariota will be shut down for the season. - - - Matt Cassel is out and Kellen Moore takes over as starting quarterback for the Dallas Cowboys, who will start four different quarterbacks in a season for the second time in franchise history. Cassel was 1-6 and Brandon Weeden went 0-3 before the Cowboys released him. Moore completed 15 of 25 passes for 158 yards, one touchdown and three interceptions in the Cowboys' 19-16 loss to the New York Jets on Saturday. - - - Seattle Seahawks running back Marshawn Lynch, recovering from surgery associated with a sports hernia injury, is not returning to practice this week. Seahawks coach Pete Carroll, during his weekly appearance on 710 ESPN Seattle, did not provide a timetable for when Lynch would be ready to return. - - - An irritated Denver Broncos quarterback Peyton Manning refuted a report that he told the team he did not want to be a backup, whether it was in practice as he works to return to the field or in games. NFL Media's Ian Rapoport reported Sunday morning on NFL Network that Manning has no interest in serving as the backup to Brock Osweiler. On Sunday night, following the Broncos' 34-27 loss to the Pittsburgh Steelers, Manning was asked for a response to the report as he exited the locker room to speak to Steelers owner Dan Rooney. "It's bull----, and it's insulting," Manning told Jeff Legwold of ESPN.com. Asked if the comment was for the record, Manning said: "Yes, and I can't say it any plainer than that." - - - The New England Patriots are expected to sign free agent running back Steven Jackson, according to multiple reports. The Patriots have been hit hard by injuries at running back this season, with the latest casualty being LeGarrette Blount a week ago after he suffered a hip injury in Week 14 that ended his season. - - - The Atlanta Falcons reached an injury settlement with guard Jon Asamoah. The move saves the Falcons $3.5 million in cash and $1.9 million in cap space next year, according to ESPN.com. Asamoah will be off the books in 2017. The injury settlement means he is now a free agent. - - - (Editing by Mark Lamport-Stokes)
