The Cowboys’ revolving door at the bottom of their roster continues to churn this week, as Laurent Robinson has been brought back as cover at the receiver spot and Bryan McCann has been released to open a roster spot. Robinson had been signed before the first week of the season, but he was cut so that the club could bring back Tony Fiammetta … who had also been cut days before.

Dallas needs depth among their receiving corps after Dez Bryant missed Week 2 with a groin injury and Miles Austin re-injured his hamstring in Week 3. That could leave them with Kevin Ogletree and Jesse Holley starting against Washington Monday night, with rookie Dwayne Harris and Robinson as their backups.

McCann slipped quickly, struggling badly against the Jets, then not playing on defense against the 49ers despite numerous injuries at corner. He had been a cult hero of sorts after his big defensive and special teams returns for touchdowns helped Jason Garrett turn the season around in the season’s second half.
