With offensive tackle depth now a question following the season-ending injury to Jason Peters, the Eagles might turn to a familiar face. 

The Eagles are working out defensive lineman turned offensive tackle Taylor Hart, a league source confirmed to NBC Sports Philadelphia. NFL Network's Ian Rapoport first reported the workout. 

The possibility of bringing in Hart makes a lot of sense. His conversion from DT to OT went very well this summer and he was the final offensive lineman to be cut as the team kept just eight. 

With his years in the league as a defensive player, Hart was ineligible for the practice squad so he has been without a team since early September. The Eagles would obviously want to check to see what kind of shape he's in before signing him. 

"All my grades on Taylor, when he was here, were very high," offensive coordinator Frank Reich said on Wednesday afternoon. "This is a tough business, only so many spots. But I was very impressed with Taylor through OTAs and training camp and thought he showed a lot of good signs."

If Hart is signed, he'll be a depth piece at tackle, along with Isaac Seumalo. The Eagles could also call up Dillon Gordon, who has been on the practice squad all season. 

Hart was originally a fifth-round pick of the Eagles in the 2014 NFL draft. He was a defensive tackle from Oregon at the time.
