In the fourth quarter of the game between the Arizona Cardinals and St. Louis Rams, quarterback Carson Palmer left the game with a knee injury and, after testing on Monday, it has been announced he suffered a torn ACL in his right knee and will miss the remainder of the season.
On a third down play in the fourth quarter and the Cardinals driving, Palmer dropped back to pass and fell down without any apparent contact.
He walked with help off the field, but stumbled once he got to the sideline.
He was taken to the locker room on a cart. Arizona was down 14-10 at the time and the "sack" gave the Cardinals a 53-yard field goal attempt. Chandler Catanzaro missed it wide right.
The Cardinals were able to rally behind a Drew Stanton touchdown pass to John Brown and two defensive scores in the fourth quarter to pull away and finish with a 31-14 win on Sunday.
NFL reporter Albert Breer tweeted "it was feared" Palmer tore his ACL in the same knee he had surgically reconstructed in 2006.
Bruce Arians and Palmer both addressed the media on Monday and it was confirmed Palmer would miss the rest of the season (via AZCardinals.com).
"It was just was a freak thing," Palmer said. "I've been in that position hundreds, if not thousands, of times."
He said he knew it was the ACL when it happened. He said he felt a pop.
Only the ACL was damaged and he hopes to be able to participate in OTAs in the offseason, which would be next June.
Palmer just signed a new contract extension on Friday that will pay him $20.5 million by the end of next season.
Obviously the timing is not good.
In an eery coincidence, Palmer suffers his knee injury just after signing a new contract. ESPN's Adam Schefter pointed out Palmer suffered his first knee injury just 10 days after signing the $119 million deal he got from the Bengals.
Palmer will be placed on injured reserve and Drew Stanton will be the starter for the rest of the season.
