Austin (concussion) was listed as a full practice participant Thursday, Teresa Varley of the Steelers' official site reports.
After being limited Wednesday, Austin's full participation a day later bodes well for his chances of being available Sunday against the Browns. He'll still need to receive clearance from an independent neurologist before exiting the NFL's five-step concussion protocol, and Friday's injury report should clarify whether or not he was able to do so.
