Mankins reportedly played in the Super Bowl with a torn ACL (US PRESSWIRE)

Patriots guard Logan Mankins underwent knee surgery to repair his anterior cruciate ligament in the weeks following New England's Super Bowl XLVI loss to the New York Giants, according to a report from ESPNBoston.com's Mike Reiss.

The procedure and subsequent rehabilitation could make Mankins' participation in minicamps and other offseason workouts unlikely, although the 2005 first-round pick hopes to be ready for the start of training camp. It's the same knee Mankins injured late in the regular season against the Dolphins forcing him to miss Week 17. The original injury occurred after his knee collided with a helmet.

One source told Reiss that Mankins' injured knee took a hit early in the Super Bowl, and later it was determined he had played through a torn ACL.

On Monday, the Patriots signed Robert Gallery, formerly of the Seahawks and the one-time first-round pick of the Raiders, perhaps as insurance in case Mankins' rehab takes longer than expected.

Last August, New England signed Mankins to a six-year, $51 million contract that included a $20 million signing bonus. At the time, the deal made him the league's highest paid interior linemen, a distinction now held by Buccaneers guard Carl Nicks.
