The Baltimore Ravens have announced that starting quarterback Joe Flacco tore his ACL during the team's 16-13 win over the St Louis Rams this evening.
The 30-year-old finished the game despite picking up the injury, helping set the team up for a late field goal to clinch the victory at the M&T Bank Stadium.
Head coach John Harbaugh confirmed in his post-game press conference that the former Super Bowl MVP will miss the remainder of the 2015 season as a result of the injury.
Flacco has not missed a regular season game since being drafted by the Ravens in 2008.
