Urquidy pulled himself from an appearance in a minor-league game Friday due to right elbow discomfort, Chandler Rome of The Athletic reports.
Urquidy -- who threw 43 pitches in the outing before exiting -- is being examined by the Astros trainers Friday. The team reportedly was already on the lookout for rotation help with Justin Verlander (shoulder) opening the season on the injured list, and a serious injury to Urquidy could increase the urgency to sign someone like Blake Snell.
