Dolphins quarterback Gus Frerotte rejoined practice on a limited basis yesterday, an indication he'll probably start at Cleveland despite a sprained right index finger.

"We feel like he probably could play in the game, based on what he did today," Coach Nick Saban said.

Frerotte didn't participate fully in team drills, and backup Sage Rosenfels remains an option for tomorrow. Saban declined to say which quarterback will start, hoping to create some doubt for the Browns.

"If you had a gun, put it to my head and you say, 'I'm going to shoot you if you don't tell me,' I probably would tell you," Saban said. "But absent the gun, I just said what I am going to say, because if I tell you I tell everybody."

* BILLS: J.P. Losman will start at quarterback for Buffalo against San Diego after Kelly Holcomb missed his third straight practice since getting a concussion. Coach Mike Mularkey said he expected Holcomb to be medically cleared for the game tomorrow, but wasn't sure if he would serve as Losman's backup or be the number three quarterback.

"To be on the safe side, we'd probably look at him being number three as we speak," Mularkey said.

Holcomb was hurt when he was sacked and fumbled in the second quarter of Buffalo's 14-3 win against Kansas City last Sunday. It was Holcomb's fifth consecutive start since replacing Losman, who struggled in opening the season at 1-3.

* CHARGERS: Outside linebackers Shawne Merriman and Steve Foley returned to practice yesterday, and both are expected to play when San Diego hosts Buffalo. Merriman, a rookie who leads the Chargers with five sacks, was able to work out after sitting out Thursday's practice with a migraine headache. He said the pins inserted into a dislocated bone in his left wrist Nov. 7 won't keep him from playing tomorrow against the Bills.

* COLTS: Safety Bob Sanders and wide receiver Brandon Stokley are expected to play tomorrow against Cincinnati after missing practice time this week because of injuries.

The Colts' defense and kick coverage squads could get another boost if linebacker Rob Morris is able to play after going through his first regular practice yesterday. He missed two games with an inner-ear infection.

* CARDINALS: Arizona moved strong safety Ernest Shazor from the practice squad to the 53-man roster and released wide receiver-kick returner J.J. Moses.
