PHILADELPHIA (AP) Eagles center Jason Kelce will miss at least four to six weeks because of a tore knee ligament, and it's possible he could face season-ending surgery.

Kelce injured his right knee in Philadelphia's 24-23 win over Baltimore on Sunday. An MRI on Monday revealed he tore his medial collateral ligament and has a partial tear of the anterior cruciate ligament.

Eagles head athletic trainer Rick Burkholder said Kelce's MCL needs at least four to six weeks to heal. Kelce will undergo further testing on Tuesday to determine whether his ACL needs to be reconstructed. If so, he'll miss the rest of the season.

Dallas Reynolds replaced Kelce, taking his first NFL snap after spending three seasons on the practice squad.
