St. Louis Rams quarterback Marc Bulger failed medical tests and has been ruled out for Sunday's game against Atlanta.
The news comes four days after Bulger sustained a concussion against the Seattle Seahawks. He left the game in the first quarter and didn't return. A day later he said he felt much better and expected to play against the Falcons, but backup Gus Frerotte said yesterday that Bulger still looked groggy.
The 2-and-9 Rams took steps in case Bulger was not cleared, and elevated Brock Berlin from the practice squad as the potential backup behind Frerotte.
