Atlanta right-hander Tim Hudson hit Polanco with a pitch in the first inning. Polanco remained in the game until Wilson Valdez pinch-hit for him in the seventh. Polanco said X-rays revealed no fracture.
"It's stiff now; weak, sore," Polanco said.
Polanco said he will not know if he can play in Thursday night's series finale until he arrives at the ballpark.
"It might be a day," Polanco said.
But one game missed is better than two or three weeks missed, right?
"Of course, without a doubt," Polanco said. "But zero days is better than one."
