Rudy Gay took an elbow to the top of his mouth in the third quarter of Team USA's win over Lithuania on Thursday.

"I've got a fracture in my jaw, a broken tooth and am going to probably need a root canal," Gay said. "The top is where I got hit. It's painful. It's uncomfortable, and it still bleeds, so I've got to continuously gargle. It is what it is, man.

"I think (the elbow) had a little bit to do with (the situation afterward)," Gay said. "It was a dirty play, man. It was a dirty play."

Gay had to receive treatment into the night before traveling to Madrid for the gold medal game.
