Buffalo Bills release Colin Brown, promote Mark Asper to active roster

The Buffalo Bills continue to re-tool their offensive line. Doug Legursky emerged as the starting left guard in Sunday's loss to Cincinnati, leading to today's announcement that the team had released his predecessor, Colin Brown.

Doug Marrone and Pat Morris had staged a left guard competition in training camp, and Brown ran away with that contest even before Legursky was injured in the team's preseason finale. In his first five starts of the regular season, however, Brown struggled mightily in every facet of the game. When Legursky returned to full health, the team didn't waste much time getting him back into the lineup.

Now, Legursky is entrenched at left guard, and the team has replaced Brown on the 53-man roster with 2012 sixth-round pick Mark Asper, a guard that the team re-acquired in September as a member of the practice squad. It's the second time in as many weeks that the Bills have made a depth move up front, following last week's release of Sam Young (now with Jacksonville) and the acquisition of reserve interior lineman Antoine McClain.
