JACKSONVILLE, Fla. — Jaguars receiver Mike Walker was in a hospital Monday with an infection in his right knee, a setback that could sideline him a few games.

Walker, who has 12 catches for 161 yards this season, sprained the medial collateral ligament in his knee Oct. 5 against Pittsburgh and did not travel with the team to Denver this past weekend.

Coach Jack Del Rio said Walker was hospitalized to receive treatments of antibiotics in hopes of reducing the infection his joint. Del Rio said Walker did not have surgery or an open wound.
