Nick McDonald with the Packers.With their depth thinned at center, the Patriots plan on promoting guard/center Nick McDonald from the practice squad on Saturday, according to a league source.

McDonald, 24, has spent most of the season on the practice squad. He began his career in Green Bay as an undrafted free agent from Grand Valley State, and spent all of last season on the Packers' 53-man roster, but was inactive for every game.

Ryan Wendell, who started last week in place of Dan Connolly (groin), has a calf injury, leaving McDonald as the third option at center. Both Wendell and Connolly are questionable for Sunday's game against the Colts.

The Patriots will have to make another roster move to clear a spot on the 53-man roster for McDonald.
