ST. LOUIS (AP) -The St. Louis Rams have lost leading wide receiver Keenan Burton for the rest of the season, the result of a right knee injury in Sunday's 28-23 loss to New Orleans.

The Rams placed Burton on injured reserve Monday with a torn patella tendon. Coach Steve Spagnuolo says Burton will have surgery on the kneecap.

Burton, a second-year player out of Kentucky, was hurt on a pass in the first quarter when he fell awkwardly in the end zone while the Saints' Usama Young made an interception.

Burton led the Rams with 25 catches for 253 yards. Two other receivers, veteran Laurent Robinson and rookie Brooks Foster, were also lost to injury this season

St. Louis (1-8) hosts Arizona this weekend.
