The Miami Dolphins placed Richard Marshall on injured reserve today, which will end his season. Marshall has been bothered by a back injury since Week 4 and has not played since then.

Taking his place will be journeyman cornerback, Brandon McDonald, who spent the year on the Tampa Bay Buccaneers, before being waived yesterday. McDonald has totaled 21 tackles on the year and has gotten an interception; he is ranked by Pro Football Focus as the 91st best CB.

McDonald played college ball at Memphis and has played six seasons in the NFL. He was drafted by Cleveland and spent 3 years with the Browns before spending a year with Arizona, two years with Detroit and the first half of this year with Tampa Bay.

McDonald will likely need to step up and play a decent role sooner than later; Miami needs as much depth as possible at the CB position- they are coming off a horrible performance in which Andrew Luck torched the secondary for a rookie record 433 yards passing.

This is the second move Miami has made this week to get fresh legs at the CB position. Earlier in the week, the Dolphins waived CB De'Andre Pressley to make room for CB Bryan McCann.
