Dolphins injuries: Richard Marshall misses second straight day of practice

Miami Dolphins starting cornerback Richard Marshall missed his second straight day of practice Thursday, as he continues to recover from a back injury.

Marshall has been battling his back injury for weeks. It would be a big blow to the Dolphins if he is unable to play on Sunday, as the Dolphins go up against Andy Dalton, A.J. Green and the rest of a powerful Cincinnati Bengals pass offense.

Cornerback Nolan Carroll (Achilles) and linebacker Kevin Burnett (foot) were able to participate in practice Thursday after they were both unable to practice on Wednesday.

Dolphins running back Reggie Bush was a limited participant in practice for the second straight day, as he continues to recover from a hip injury.

Defensive tackle Tony McDaniel and linebacker Austin Spitter were both limited in practice Wednesday, while Paul Soliai and Marlon Moore were full participants. Their statuses for practice on Thursday were not available
