PITTSBURGH -- Rashard Mendenhall's surgically repaired right knee is just fine. So too it seems is the Pittsburgh Steelers' running game.

Cutting with authority and showcasing the explosiveness that made him a vital part of Pittsburgh's offense, Mendenhall rolled up 101 total yards and a touchdown in Pittsburgh's 16-14 victory over Philadelphia on Sunday.

Playing for the first time since tearing the ACL in his right knee on New Years Day, Mendenhall revived Pittsburgh's beleaguered running game to take some of the pressure off Roethlisberger. The Steelers (2-2) came in 31st in the league in rushing yards per game and dead last in yards per carry.

Mendenhall took care of that, averaging a robust 5.8 yards on 14 carries, not including a 29-yard run wiped out by one of Pittsburgh's nine penalties.

He was just as effective out of the backfield, catching two passes for 20 yards, including a 15-yard screen pass during Pittsburgh's final drive that ended with Shaun Suisham's 34-yard field goal as time expired.
