Update: Alexi Casilla is in the Orioles clubhouse with his right thumb wrapped. He said it was frightening to watch the replay of his collision with teammate Nick Markakis in yesterday's game, and that he passed a CT scan performed Monday night.
Casilla, however, doesn't remember the play or how he got back to the clubhouse. He did fly back to Baltimore with the team. The original plan was that he'd be held overnight in St. Petersburg, Fla., for observation before rejoining the Orioles.
Casilla is still trying to clear his head and asked that no TV cameras with lights film him in front of his locker because he's still sensitive to brightness. Because he is experiencing concussion symptoms, he will have to go through Major League Baseball's new guidelines before returning to action.
