Source: Pats work out OL McDonald

The Patriots had a familiar face in for a workout Tuesday. Offensive lineman Nick McDonald, waived by the team July 31 after two seasons in New England, was brought in for a look, according to a source.

McDonald, who has experience playing all five positions along the offensive line, is a former undrafted free agent out of Grand Valley State who served in a reserve role for the Patriots last season.

The team was left with just one reserve offensive lineman at the conclusion of Sunday night's game, as Marcus Cannon left the game with an ankle injury and did not return. Veteran Will Svitek took over for Cannon at right tackle, leaving Josh Kline as the only other active reserve lineman.

The Patriots have rookie Chris Barker on the roster to suit up if Cannon is forced to sit out this Sunday's game against the Texans, but McDonald's experience at tackle could be one of the reasons the Patriots were interested in working him out. Both Barker and Kline are interior players.

After waiving both defensive tackle Marcus Forston and Justin Green, the Patriots have two open spots on their 53-man roster. One of those will be filled by tight end D.J. Williams, who a league source confirmed will sign with the team.
