Jason Kelce discusses what he's 'regretting' about retirement

"Social media has been nonstop, saying 'Jason, you sure you wanna retire?' And I'm like 'Yeah, I'm pretty positive.' Even though I'm a little upset Howie waited until I retired to make a move like this! But you know it's fine, it'll work out great," the elder Kelce brother said. "We talked about it last week. This is what I'm regretting. I knew when I retired that I was going to miss just an outstanding season for the Philadelphia Eagles. And it sucks, it really does. I wanna be a part of this so bad, I wish I could, but it doesn't suck in the way that I get to still, like 'Hey, I'm a Philadelphian. I get to watch it and celebrate it just like everybody else. So I'm excited for that."

The 36-year-old Kelce announced his retirement last week, shortly before the New York Giants decided not to place the franchise tag on Barkley, making him a free agent.

It was reported on Monday that the Eagles and the former AP Offensive Rookie of the Year had agreed to a three-year contract.

Philadelphia also saw their leading rusher from last season – Pro Bowl back D'Andre Swift – agree to a contract with the Chicago Bears on Monday.
