Desmond went out to the field to play defense for the bottom of the inning, but he didn't have a good feel for the ball and was then taken out of the game.
"He is fine. X-rays were negative," manager Matt Williams said. "He is a little sore. Initially, when you get hit like that, it's difficult to grab a ball, so he was trying to throw the ball and he didn't have a good feel for it. So we got him in [the clubhouse] and got a picture. He is fine."
Desmond was replaced by Danny Espinosa, who could see time at shortstop if Desmond is unable to play against the Phillies this weekend.
