According to the Baltimore Sun’s Jeff Zrebiec, the Ravens have spoken to impending free agent Crockett Gillmore about a return.
The Ravens have spoken to TE-turned-OL Crockett Gillmore, another of their pending UFA's, about a return. They'd just have to be comfortable about where he's at physically, but he appears the most likely of their UFAs to return.

This is a rather interesting situation as Gillmore will be switching positions for next season. Instead of tight end, he will attempt to be an offensive linemen, most likely a right tackle.
