Carey Davis, a first-year free agent, has supplanted Dan Kreider as the No. 1 fullback and will start in the season opener against the Cleveland Browns.
Offensive coordinator Bruce Arians confirmed the move today after the Steelers finished practice at their South Side facility.
It is possible Kreider, the starter for the past five seasons, might be deactivated against the Browns.
"Everything is week to week, but he will be the fullback," Arians said of Davis. "He's doing a nice job for us."
