Giants C Shaun O'Hara underwent his second surgery of the offseason, according to ESPN NewYork.
O'Hara underwent a procedure to clean out his left ankle and Achilles tendon this week. In January, he had a couple of screws placed in his right foot. He suffered a Lisfranc injury in 2010 and played in just six games.
The 12-year veteran said earlier in March that he will be 100 percent for training camp.
Rich Seubert, who filled in for O'Hara, is recovering from offseason surgery to repair a dislocated kneecap and backup C Adam Koets, who tore his ACL, is doing the same.
