Anderson may not make his scheduled start Sunday and could be headed to the disabled list, according to Bob Nightengale of USA Today. However, Anderson threw Saturday and said he "feels good," according to Nick Groke of The Denver Post, so it appears he could still take the ball.
Anderson's status for Sunday's start is now clearly in question, but it's too early to estimate whether or not he will be able to take the ball. More details should become available in the near future, but if Anderson does wind up on the disabled list, Nightengale indicated Jeff Hoffman would be called up to start in his place.
