Phillies left-fielder Domonic Brown will have his back examined Thursday after he felt a pop diving for a ball on Wednesday at Great American Ball Park.

Brown does not believe it is serious.

"I don't know what happened," said Brown, who dove for a ball in the first inning in an 11-2 loss to the Reds. "We're going to get an MRI and see exactly what's going on. I don't think it's anything major at all."

But Brown added, "I felt some pain immediately. Once I took a couple of swings, I really felt it."

He left the game in the fourth inning.
