From the MLB website:
Marcus Giles arrived at the ballpark with a swollen and stiff left middle finger. Giles, who was injured while sliding into second base on Tuesday night, will learn the extent of the injury after having an MRI performed in Atlanta on Thursday morning.
Although X-rays that were taken Tuesday night didn't show a fracture, Giles may learn that there is some ligament damage. His swollen finger was wrapped in a brace on Wednesday morning.
It is likely either Giles or Renteria will wind up on the DL, because otherwise the Braves would be seriously shorthanded. This sucks.
Giles, Huff, Crisp, C. Jones, Baldelli -- my roster can't take much more!
