Andino, who took a 94-mph fastball to the back of his helmet from Mark Melancon, went to a local hospital after Friday's game to get a CT scan, the results of which were negative.
He was scheduled to take a concussion test before today's game. He'd have to pass that before he's cleared to play.
Orioles manager Buck Showalter said he's optimistic that if cleared Andino would return to the starting lineup on Sunday.
After Andino was hit, he took a few steps toward the mound before Showalter and team trainer Richie Bancells ran out to treat him.
Andino wasn't made available to the media following Friday's game and was waiting to see doctors before Saturday's game.
Other news to note:
-- Showalter said he stayed with Darren O'Day in the eighth inning of Friday's game instead of pitching Pedro Strop because he wanted the give Strop an extra day of rest. He said there's no health concern with Strop and it wasn't a sign that his eighth-inning set up role is in doubt. But Strop has obviously struggled recently so it will be interesting to see how he's used moving forward.
-- Showalter still hasn't made a decision on the second starter for Monday's doubleheader against the Blue Jays. Left-hander Wei-Yin Chen will start one of the games. It appears the right-hander Steve Johnson would be a likely candidate. The other starters for the Blue Jays series have yet to be announced, but it would seem that Joe Saunders would start Tuesday. Showalter said Miguel Gonzalez could start Wednesday on regular rest.
