ORCHARD PARK, N.Y. — Buffalo Bills receiver Roscoe Parrish will miss four to six weeks after having surgery to repair ligament damage in his right thumb.

Coach Dick Jauron said Wednesday that Parrish was hurt during the fourth quarter of a 24-23 win over Oakland last weekend. Parrish continued playing and scored on a 14-yard catch, which cut the Raiders' lead to 23-21 with 4 minutes left.

The Bills (3-0) play at St. Louis this weekend.

Jauron said the operation Tuesday was brief but intricate. He said the injury was so severe there were initial concerns that Parrish could miss the entire season.

Parrish has seven catches for 60 yards and a touchdown as the No. 3 receiver, and also scored on a 63-yard punt return.
