The news on the latest injury to a Steelers quarterback may not be as good as team officials had hoped Sunday night after Dennis Dixon's left knee was injured in their 19-11 victory at Tennessee.
One source close to the situation told the Post-Gazette that Dixon has a torn lateral meniscus, which could keep him out 3-5 weeks.
Coach Mike Tomlin said after the game he did not know who would start Sunday in Tampa Bay against the Bucs.
Byron Leftwich returned to the team Monday and said he would push his knee hard in practice to see how it responds. Leftwich's left MCL was sprained in the final preseason game Sept. 2. He threw some passes in practices last week.
Charlie Batch, who replaced Dixon and finished the final three quarters Sunday in Nashville, remains the only healthy quarterback on the roster.
