Rockies starter Tyler Chatwood is expected to miss at least one start because of pain in his triceps.
Chatwood had to leave a 3-0 loss to the Cincinnati Reds on Monday night after pitching only four innings because of pain in the muscle when he threw his fastball. He flew to Denver on Tuesday and had a medical examination that left the Rockies optimistic there's no serious damage.
He was scheduled for an MRI later in the day.
Manager Walt Weiss said the initial reports on Chatwood were ''pretty good.'' The club will decide what to do after it gets the MRI results. Weiss said it would be tough for Chatwood to make his next scheduled start under the circumstances.
