Wilcots: Two games is enough
The Steelers also have longtime backup Charlie Batch and third-year pro Dennis Dixon under contract at quarterback. Batch has been injured each of the past two seasons. Dixon has started only one NFL game, but he likely would compete with Leftwich in training camp to be the early season starter if Roethlisberger is suspended.
Roethlisberger was accused of sexually assaulting a 20-year-old female college student in a Georgia nightclub last month, but he will not face criminal charges.
Leftwich started Tampa Bay's first three games in 2009 before Josh Johnson replaced him. Leftwich completed 58 of 107 passes for 594 yards and four touchdowns with three interceptions before being placed on injured reserve with an elbow issue.
