San Diego Chargers kicker Nate Kaeding will undergo an MRI exam on Monday for what the team fears is a torn ACL in his left knee.
Kaeding was hurt while trying to make a tackle on Percy Harvin's 103-yard opening kickoff return Sunday.
He was carted off the field and punter Mike Scifres assumed all kicking duties Sunday.
Kaeding has been among the league's best kickers since he was drafted by the Chargers in 2004. He has converted 86.5 percent (173-for-200) of his field goal attempts in his seven seasons.
