Cornerback Roc Carmichael, who spent the 2013 season and the 2014 preseason with the Eagles, was re-signed to the active roster Tuesday after the team placed safety Earl Wolff on injured reserve.

Carmichael, 26, was originally a fourth-round pick of the Houston Texans in the 2011 NFL Draft. He has played 19 games in his career, including 13 with the Eagles. He started at cornerback twice for the Eagles last season, recording three passes defensed. Carmichael also played extensively on special teams for the Eagles last season.

Eagles head coach Chip Kelly said Tuesday the Eagles had Carmichael in for a tryout Friday, and the coach liked what he saw.

"Roc looked like he was moving around, doing things well, and he has experience in our system," Kelly said.

He was released by the Eagles as part of the final roster cutdown on August 30.

Wolff, the 25-year-old second-year player, played in seven games for the Eagles this season, starting once.

Wolff said after Tuesday's training session that the injury had nagged him all season long, but he tried to push through it until he could no longer do so.

"It's been kind of on and off, I had my good days and I had my bad days," Wolff explained. "We just came to the conclusion that the best thing for me is to rest and get ready for next year."

Despite the shared surname, Carmichael and Eagles great Harold Carmichael are not directly related.
