All-Pro LT Jason Peters re-injures Achilles
The Eagles confirmed the injury Monday. Peters was already out indefinitely and is likely to miss the 2012 season.
A five-time Pro Bowl selection, Peters is widely considered one of the best offensive linemen in the NFL. He spent his first five seasons with Buffalo before coming to Philadelphia in 2009.
The Eagles had no other details on Peters' latest setback. He injured his leg the first time while training in Texas.
