Baltimore Ravens quarterback Joe Flacco will miss the rest of the season with a torn ACL suffered late in Sunday's win over the St. Louis Rams.
Flacco may have also torn his MCL, the team announced.
The injury occurred when Flacco was rolled up on by a lineman with seconds remaining on the clock. Flacco was able to run two more plays, setting up a game-winning field goal by Justin Tucker, before walking off the field with a pronounced limp.
The injury is the latest setback in a disastrous campaign for the Ravens. The team also lost Terrell Suggs and Steve Smith to Achilles injuries, and Justin Forsett to a broken arm.
Flacco has never missed a game in his eight-year career. Matt Schaub is expected to start in his place in Week 12.
