McCoy has two seasons remaining on his deal.
Another important deadline is October 30, the date by which National Football League teams can make in-season trades.
The Eagles now have just over $4.3 million in cap space.
McCoy, 30, spent his first six seasons in Philadelphia rushing for at least 1,000 in four of those.

While Bell is looking for a big money contract next offseason, and he claimed over the weekend he does not want to be traded ... if the Eagles want to get back to the Super Bowl, they'll need to amplify the running game.
Ajayi was reportedly injured in the Eagles' 23-21 loss to the Minnesota Vikings on Sunday.
Adding either Johnson or Bell would take a serious hit to the Eagles payroll this year and beyond.
The season, and possibility the entire tenure with the Eagles, is now over for Ajayi, who is in the past year of his contract. Or, of course, they could try to pursue trades for other, cheaper running backs or simply sign an existing free agent.
