Gray originally injured his foot during Spring Training. However, he aggravated it against the San Francisco Giants on April 13 as he jumped up to try to field a bouncing ground ball.
Gray was able to finish the inning, but never came back to pitch in the fourth.
This was and is a major blow to the Rockies starting rotation. Gray was supposed to be the ace of the rotation, but who knows how this injury will affect the Rockies (and more importantly Gray) when he returns.
However, we can only worry about the present. So my question is, who should replace Jon Gray until he returns from the disabled list?
