PHILADELPHIA (973espn.com) - The Eagles have started a 21-day practice window for cornerback Cre'Von LeBlanc and the veteran corner could be activated off injured reserve by  Sunday's game against the Miami Dolphins in his native South Florida.

LeBlanc suffered a Lisfranc foot injury back in training camp and was placed on injured reserve. He is the first of two players the Eagles could bring back from injured reserve after sitting out a minimum of eight games.

“I was hoping to get back sooner, but people heal different and it was slowly but surely. I just wanted to make sure it was right," LeBlanc said at his locker on Tuesday.

Philadelphia is all of a sudden very deep again at the CB position as a whole after suffering some major issues early in the season due to injuries to LeBlanc, as well as Jalen Mills, Ronald Darby and Avonte Maddox.

Slowly but surely Jim Schwartz started getting his most trustworthy players at the position back starting with Mills on Oct. 20 in Dallas. From there Darby returned from a hamstring issue and Maddox made it back from a neck/concussion injury and the Philadelphia defense has taken off, allowing 17 points or fewer over the past four games.

"It will be nice to have him back." Schwartz said. "He was an important member of our defense last year, and we certainly have roles that he can fill.”

LeBlanc figures to backup Maddox as the slot CB while Rasul Douglas and Sidney Jones will be behind Mills and Darby on the outside, although Jones is probably the odd man out when it comes to dressing once LeBlanc is put on the 53-man roster.

“We’ll take it one day at a time, see what he looks like physically,” Schwartz said. “He's only been working on the side with trainers, so he's never been out with not only the position coaches, but also against other players. So we need to see what he looks like that way, but if he looks good, then we'll get him back into the swing as quick as we can."
