The Steelers reacquired quarterback Byron Leftwich by dealing a seventh-round draft pick to Tampa Bay, a sign they expect Ben Roethlisberger to be suspended for the start of the season. Leftwich backed up Roethlisberger in 2008, when the Steelers won the Super Bowl. He knows offensive coordinator Bruce Arians' system and could be ready to play Sept. 12 when the Steelers open against Atlanta.
