ST. LOUIS (TICKER) -- St. Louis Rams quarterback Marc Bulger had a setback on Friday and he is listed as questionable for Sunday's game against the Cincinnati Bengals.

Bulger, who was recovering from a concussion, was cleared to practice on Tuesday. He practiced on Wednesday and Thursday, but did not feel well shortly thereafter. He practiced on a limited basis on Friday.

"Marc had really - what I thought - were two very good practices Wednesday and Thursday, but that's the objective part," Rams coach Scott Linehan said.

"I guess the subjective part is he didn't feel really good after (those) meetings. Because of that, it puts some questions in my mind as to whether or not he should be cleared to play. We're not going to put a guy out on the field if there's any doubt whatsoever when it comes to these kinds of injuries or any injuries."

Bulger, who suffered the concussion in a win over Seattle on November 25, has endured an injury-plagued campaign, also missing two games with broken ribs. The 30-year-old Bulger has six touchdown passes and nine interceptions in nine games this season.

The potential loss of Bugler is especially painful since backup signal-caller Gus Frerotte has a partially torn labrum in his throwing shoulder and isn't expected to play Sunday.

That means that the Rams (3-9) will turn to 26-year-old Brock Berlin, who will likely make his first career start. A third-year player out of Miami, Berlin has never played in an NFL game.
