Mankins, 31, still has three years remaining on his six-year, $51 million contract. However, a contract extension could offer them some cap relief in the time being. He’ll make $6.25 million for the 2014 season as things stand right now.
Last year, Mankins appeared in all 16 games for the Patriots and was rated as the No. 19 guard in the league, according to Pro Football Focus.
