Bush strained a calf muscle, but there is no tear, reports Schefter. Bush left his first game with the 49ers in the first quarter of Monday night’s season-opening win against the Minnesota Vikings. He was carted from the sidelines to the locker room and did not return after rushing twice for eight carries.
Without Bush, the 49ers were left with Carlos Hyde and former Australian rugby player Jarryd Hayne at running back. Hyde rushed 26 times for 168 yards and two touchdowns; Hayne rushed four times for 13 yards and fumbled on his NFL touch, a punt return.
Now in his 10th NFL season, Bush has dealt with injuries throughout his career. He last played a full 16 games in 2012, with the Miami Dolphins, and also did the same as a rookie in 2006 with the New Orleans Saints.
The 49ers will play the Steelers in Pittsburgh on Sunday.
