Rams' Xavier Smith: Returns to full participation

Smith (concussion) logged a full practice Wednesday, Adam Grosbard of The Orange County Register reports.

Smith missed the Rams' Week 12 win over the Buccaneers after logging a pair of limited practices. His return to a full session Wednesday is positive, but it's unclear if he has cleared the league's concussion protocol -- a necessary step before he can return in Week 13 against the Panthers.
