Monday, Packers right tackle Earl Dotson was to undergo an MRI on his sore back, which forced him to the inactives list for the first time of the season Sunday.

GM/Head Coach Mike Sherman said that team doctors didn't expect to find any new damage, but hoped to discover a clue that might help in rehabbing the 10-year veteran, who missed most of the 2000 season with back troubles.

Dotson is one of two players Sherman expects will be listed as questionable this week, the other being nose tackle Gilbert Brown, who has missed the last three weeks with an ankle injury.

The rest of the Packers' squad emerged from the weekend without too much pain.

Running back Tony Fisher suffered a bruised shoulder and wide receiver Terry Glenn sustained minor injuries to his elbow and rib, but both are probable for Sunday's game against the Buffalo Bills.

Also probable is starting tailback Ahman Green, who racked up 90 yards rushing in his first game back from a knee injury.

Sherman said he would likely have Green sit out of Wednesday's practice to allow an extra day of recovery.

"When you watch him run, he is a punishing runner, not only to his opponents but to himself as well," Sherman said. "I think it's in my best interest for this team to monitor him in practice and keep him limited."

If the Packers are without Dotson this week, he would likely be replaced in the starting lineup by rookie Kevin Barry.

Barry made his first NFL start Sunday in San Francisco.

"I thought Kevin did a nice job," Sherman said of Barry's performance. "You certainly would rather have the veteran player in the game over a rookie player, but Kevin certainly did nothing in the ballgame to disappoint me or cause me to have a lack of confidence if in fact he is going to be the starter in the absence of Earl Dotson."
