ORCHARD PARK, N.Y. -- Cornerback Terrence McGee needs more tests on his sprained left knee, leaving his status uncertain for the undefeated Buffalo Bills' game at Arizona this weekend.
Coach Dick Jauron said McGee was having difficulty walking on Monday, but it was too early to determine whether the starter would miss any playing time. The AFC East-leading Bills (4-0), off to their best start since 1992, are off until they return to practice Wednesday.
McGee was hurt making a tackle in the first quarter of Buffalo's 31-14 win at St. Louis on Sunday. The injury forced the Bills to use nickel-back Ashton Youboty and rookie first-round draft pick Leodis McKelvin to fill in opposite starter Jabari Greer.
Buffalo limited the Rams to 213 yards passing, and Greer scored the go-ahead points when he returned a Trent Green interception 33 yards for a touchdown on the first play of the fourth quarter.
McKelvin had a solid outing getting his most playing time of the season. He finished with two tackles and forced and recovered a fumble after making a heavy hit on Rams receiver Dane Looker, who sustained a concussion.
