The St. Louis Rams, who have won three of the last four games following a disastrous 0-8 beginning to their season, are likely to have quarterback Marc Bulger back in the starting lineup this week when they play at Cincinnati. On Tuesday, Bulger, 30, passed a neuropsychological examination, and he has been cleared to return to practice on Wednesday morning. Last week, Bulger failed a similar battery of tests after suffering a concussion in the Rams' game against Seattle on Nov. 25, and he was held out of Sunday's contest with the Atlanta Falcons. Barring any setbacks, Bulger should be able to start against the Bengals. The coaches and team doctors will monitor him during the week but don't anticipate any residual effects.
