Carson Palmer out for year with torn ACL

Just two days after receiving a $50 million extension, Carson Palmer suffered a season-ending knee injury Sunday.

Arizona Cardinals quarterback Carson Palmer is out for the year after an MRI confirmed he suffered a torn ACL during the team's 31-14 victory over the St. Louis Rams, per Jay Glazer of Fox Sports.

Palmer, 34, suffered the injury after very minimal contact when Rams safety Mark Barron forced him to step up slightly in the pocket and his left knee buckled. He walked to the sideline with help, but stumbled when he got to the sideline and was subsequently carted to the locker room.

Head coach Bruce Arians remained confident that the team could still win a Super Bowl with Drew Stanton at quarterback, but also displayed some vulnerability in admitting it was a road he’d rather not take.

The injury was to the same knee Palmer suffered severe damage to as a member of the Cincinnati Bengals in January 2006, which required surgery to repair.

Just two days before the injury, the Cardinals announced a three-year, $50 million extension for Palmer with $20.5 million guaranteed through the 2015 season. The team has the option to opt out of the contract in 2016 without owing any additional money to Palmer. Coincidentally, Palmer received a long-term extension from the Bengals just 10 days before suffering his knee injury in 2006.

With Palmer now done for the year, the 8-1 Cardinals will be in the hands of quarterback Drew Stanton, who signed with the team in 2013. Stanton finished 3 of 5 for 85 yards Sunday, including a go-ahead touchdown pass to John Brown in the fourth quarter.
