Urquidy exited his rehab start at Triple-A Sugar Land on Friday due to right forearm discomfort, Chandler Rome of The Athletic reports.
Urquidy has been sidelined since spring training due to a strained right forearm, and he seems to have aggravated the issue during his outing Friday. The right-hander was expected to return to the Astros' rotation after Friday's start, but it's unclear how his latest flareup may impact his return timeline.
