Carson Palmer suffered a left knee injury in the fourth quarter of Sunday's game versus the St. Louis Rams. NFL Media's Albert Breer reported that the team believes the quarterback has torn his left ACL, which would end his season pending tests to confirm the news, per a source briefed on the injury.
This is the same knee Palmer shredded so severely in 2006 that his surgeon deemed the damage a "four" on a "scale of one to three." Coach Bruce Arians said after the game the team wouldn't know Palmer's prognosis until more tests are done.
