Soroka remained in the game as a base runner but was removed in the bottom of the third and replaced by pitcher Josh Tomlin.
The Braves announced that Soroka was taken out for precautionary reasons. Braves manager Brian Snitker said that X-rays taken on the pitcher's arm were negative.
"I think he's OK. All the X-rays were negative," Braves manager Brian Snitker told reporters. "We'll know more in a couple days when he tries to throw the ball around. They don't seem to think it's going to be [anything] other than a nice bruise."
Soroka allowed one hit and had a strikeout in the first two innings of the game. The Braves earned a 4-3 win in 10 innings.
"I knew I got it right in the flexors and as soon as those tighten up there's pretty much no chance of throwing a baseball today," Soroka told reporters. "But good news is the inflammation is going to get out of there and hopefully I'll be in line for the next start."
Soroka has an 8-1 record with a 2.07 ERA in 13 starts this season.
