PHILADELPHIA (973espn.com) - It wasn't exactly a secret but Fletcher Cox confirmed that he had offseason foot surgery on Tuesday stemming from an injury suffered in the Eagles' divisional round postseason loss to the New Orleans Saints back in January.

When last seen by reporters on cleanout day after the playoff setback the All-Pro defensive tackle was in a walking boot and the surgery report emerged in March when a picture of Cox in a boot and using a roll-about appeared on social media.

The good news is Cox was moving well when climbing ths stairs to address reporters at the NovaCare Complex media house. The bad news is that it doesn't sound like the Eagles' best defensive player is going to do much on-field work this spring.

"I had a procedure done this offseason and everything is going good, so I’m happy about that," Cox explained. “The goal is to be ready for training camp. Just take it day by day. The doctors and everyone have a schedule and I’m following what they’re doing and everything is going good so far. Training camp is the goal.”

Cox was in and out of the playoff loss to the Saints after being injured on a fake punt but toughed it out to play 42 of 77 defensive snaps in that contest.

“The main thing was to finish that game,” Cox explained. “For those guys out there, I always said, 'I’d give up a limb for those guys.'”

The page has now officially been turned on last season, however, and Cox is starting to look forward and that means a new running mate on the interior of Jim Schwartz's defense, veteran pickup Malik Jackson.

Cox hasn't talked much football with Jackson, not a surprise since Tuesday was just the second day of Philadelphia's offseason program but the presence of Jackson could make opposing offensive lines leery of sliding protection toward Cox all the time.

Another change for Cox was losing his longtime position coach Chris Wilson in favor of Phillip Daniels. Cox and Wilson have a history dating back to the star's college days at Mississippi State and he thanked Wilson for helping the Eagles get to a Super Bowl LII win but acknowledged the business of the NFL and that the shift toward Daniels, who had been Wilson's assistant, should be an easy one.

Cox is also thrilled to have Vinny Curry back in the defensive line mix and acknowledged how important keeping Brandon Graham was as well. A third piece to that puzzle is Chris Long but Cox is giving his friend plenty of space to make his own decision when it comes to a potential retirement.
