Starting quarterback Todd Collins will play about a quarter of Saturday's preseason opener in Denver, coach Marv Levy said.
Billy Joe Hobert will replace Collins at quarterback and will be followed by Alex Van Pelt and Jim Ballard.
"We plan to play them all pretty much equally," Levy said after Thursday's practice at Fredonia State College.
"It will be more by the number of plays than quarters," Levy said. "We figure it tends to work out 16 plays apiece, but it may not work out exactly like that."
Running back Thurman Thomas has very slightly bruised ribs, Levy said, and may not play at all against the Broncos. Levy said he was not sure if Thomas would make the trip.
Rookie tight end Pat Fitzgerald has a severely sprained ankle and will be out at least two weeks, Levy said.
The signing of tight end Mike Titley earlier this week was unrelated to Fitzgerald's injury.
"We had intended to bring him in because the position requires so many players since two are on the field most of the time," Levy said.
The Bills were to hold a brief 10 a.m. workout today before leaving for Denver. The team will be off Sunday. There will be one practice on Monday (at 2:30 p.m.), two practices on Tuesday (at 9:30 a.m. and 3 p.m.) and afternoon practices the rest of next week.
Don Shula receives induction into the Hall of Fame on Saturday. Levy, who owned a 17-5 record as Bills coach against Shula, commented this week on the former Miami Dolphins coach.
"I always liked the way he handled himself," Levy said. "I always felt he taught clean football and was a credit to the game. He was never the kind of guy trying to find a cheap way to win. . . . He's the same man to talk to when he's won the game or when you've won the game.
"I remember being out of a job and looking for one as an assistant on his staff many years ago," Levy said. "I called him at the East-West all-star game. He must have had 500 calls. He called me back. He didn't have an opening, but he's a guy who calls you back."
