Dolphins Place Richard Marshall on Injured Reserve and Other AFC East News

The Miami Dolphins have had trouble defending the pass all season, but their troubles just got a little more...umm, troubling.

The team announced it placed cornerback Richard Marshall on season-ending injured reserve, and in conjunction made another move to pick up cornerback Brandon McDonald from the Buccaneers practice squad.

The move signals an increasing lack of depth in the Dolphins secondary. Along with holdovers Sean Smith and Vontae Davis, Marshall was supposed to provide a solid trio of cover corners. Now, halfway into the season, the Dolphins are down to just one of those three.

Marshall played in the first four games of the year before missing the last four with a back injury. It was believed he might be good to go following the bye week but has been ruled out in both games since the team returned to action.
