Flaherty was taken to the training room, where he went through some tests -- including the SCAT3 concussion test -- and manager Buck Showalter said the team will not take Flaherty to Wednesday's game in Fort Myers.
"I think he's going to be all right," Showalter said. "Richie will be in touch with him over the night. See how he feels tomorrow."
