Miami Dolphins running back Reggie Bush was limited in Thursday practices but looks strong, according to Ben Volin of The Palm Beach Post. Volin said he had little doubt Bush will be able to play Sunday against Arizona.
Bush was seen at Thursday's practice on a bike before joining his teammates for non-contact drills.
Reggie worked with the team in non-contact drills. The way he's running, you'd have no idea he hurt himself Sunday— Ben Volin (@BenVolinPBP) September 27, 2012
Bush has 50 attempts for 302 yards on the season, giving him a 6.0 rushing average. He injured his knee against the Houston Texans in Week 3, but an MRI showed no damage.
Volin also reported that Miami cornerback Richard Marshall was not at Thursday's practice. The Dolphins starter had played in all three games but was limited in practice on Wednesday because of a back injury that occurred two weeks ago.
Marshall was the Cardinals' starting cornerback opposite Patrick Peterson last year. The seven-year veteran has played in at least 16 games in every season leading into 2012.
