BOSTON (CBS) – It’s been well noted how tough Logan Mankins is. This latest development just adds to his legend.

According to ESPN’s Adam Schefter, Mankins tore his right ACL in New England’s 2011 season opener against the Miami Dolphins, but still finished that game and the rest of the regular season.

Things got worse for Mankins when he tore his left MCL in the Pats’ divisional round playoff game against the Denver Broncos. But, the All Pro guard was still on the field the following week for the Patriots against the Ravens in the AFC Championship game and then against the Giants in Super Bowl XLVI — with a torn ligament in each leg.

On Sunday, six months removed from ACL surgery, Mankins will anchor the New England offensive line against the Titans in Tennessee.
