ORCHARD PARK, N.Y. (AP) -Receiver Peerless Price returned to practice Thursday, but the Buffalo Bills fear they could be without starting fullback Daimon Shelton against Tennessee.

Coach Dick Jauron gave Shelton ``an outside chance'' of playing after he missed his second straight practice because of a concussion sustained in a 21-0 win over Miami last Sunday. If Shelton can't play, the Bills would use reserve tight end Brad Cieslak as their primary fullback.

Jauron was more hopeful about Price, saying the No. 2 receiver worked at full speed after being held out of Wednesday's practice with a bruised quadriceps.

Both Shelton and Price are listed questionable as Buffalo (7-7) faces the Titans (7-7) in the Bills' home finale Sunday. Linebacker Takeo Spikes (ankle) is also listed as questionable, but expected to play after he practiced Thursday.

Reserve veteran guard Tutan Reyes remained excused from practice because of personal reasons. Jauron said it's possible Reyes could return by Friday.
