Do you see that bump on Gavin Floyd's elbow? That's not supposed to be there.
You might be able to notice it better when he's moving his arm:
The Braves pitcher left tonight's game against the Nationals in the seventh inning with an injury to his pitching elbow. The concerning part: Floyd had Tommy John surgery on that same elbow last year.
The bump appears to be bursitis. Here's a closer image:
The official report from the Braves' Twitter account is "posterior swelling of his right elbow." Floyd had X-rays taken and saw the Nationals' doctor. There will likely be more to this.
