Jason Peters underwent surgery to repair his ruptured right Achilles tendon, the Eagles announced Tuesday.
The surgery was performed by Steve Ralkin of the Rothman Institute and was performed at Jefferson in the Navy Yard.
Peters injured himself last Tuesday while working out in Texas. The Eagles have not set a timetable for the All Pro left tackle's return, but recovery from an Achilles injury takes on average about nine months.
The team has already begun to search for a replacement, bringing in free agent Demetrius Bell for a visit last weekend. But the Bills tackle left without a deal and is reportedly scheduled to meet with the Green Packers sometime this week.
Bell has also visited the Steelers. The Cardinals and Redskins are also said to be interested in the 27-year old. And yet, Bell remains unsigned. The Eagles are likely only looking for a stopgap until Peters return, although a full recovery from an Achilles tear -- especially for a 30-year old -- is never certain.
Marcus McNeill is considered to be one of the best free agent tackles on the market, but he has been beset by injuries over the last two seasons. Kareem McKenzie is also available, but he's 32 and a right tackle.
The next tier of free agents is rife with journeyman, part-time starters and injured tackles. That list includes Max Starks and Tria Essex of the Steelers, Barry Richardson of the Chiefs, Pat McQuiston of the Saints, Stephon Heyer of the Raiders and James Lee of the Bucs.
The Eagles re-signed King Dunlap to a one-year contract last week, but he has only three career starts at left tackle. He should be in the mix for the spot, though. There's a chance the Eagles move one of their other starters to left tackle -- right tackle Todd Herremans or right guard Danny Watkins have experience there.
The draft is three weeks away and the Eagles could always pull off a trade. But there aren't many draft prospects deemed as ready to start on Day 1, and most teams aren't looking to deal away starting-caliber tackles.
The NFL will release the Eagles' 2012 preseason opponents on Wednesday. Dates and times will be announced at a later date. While the Eagles' regular season opponents are set, the full schedule would be released until late this month.
