Freiermuth (concussion) was listed as a full practice participant Wednesday, Teresa Varley of the Steelers' official site reports.
The Steelers haven't indicated that Freiermuth has been removed from the NFL's concussion protocol, so while his full participation in practice to begin Week 13 prep is a positive sign, he may need clearance from an independent neurologist in order to play Sunday against the Ravens. With Eric Ebron (knee) on injured reserve, Freiermuth is the Steelers' clear-cut top pass-catching tight end when healthy, with Zach Gentry and Kevin Rader behind him as depth options at the position.
