New England Patriots offensive lineman Nick McDonald will soon be re-united with his brother.

Former Michigan State guard Chris McDonald, an undrafted free agent, agreed to terms with the Patriots on Saturday evening, a source confirmed.

The younger McDonald started 39 games for the Spartans, including the final 30 of his career at right guard. He was an honorable mention All-Big Ten selection last season, and was named to the preseason Outland Trophy watch list.

After losing their mother to cancer, the McDonald brothers lived on their own as teenagers and eventually were adopted by other families. ESPN.com's Liz Merrill chronicled Nick McDonald's journey to the NFL last year.
