Fletcher Cox returned to the Philadelphia Eagles' training facility this week in advance of mandatory minicamp, which opens Tuesday.
Cox skipped voluntary OTAs this offseason while seeking a long-term contract extension.
The defensive lineman released a statement saying he would not discuss his contract situation.
"I'm happy to be back in Philadelphia to get back to work with my teammates and coaches," Cox said in the statement. "I'm excited for this upcoming season and I can't wait to get on the field for minicamp this week, learn our new defense, and do whatever I can to help our team win.
