Urquidy's MRI on Monday revealed inflammation in his right shoulder, Danielle Lerner of the Houston Chronicle reports.
The Astros placed Urquidy on the 15-day injured list earlier in the day after he left Sunday's start early with right shoulder discomfort. Manager Dusty Baker stated Monday that the right-hander will be shut down from throwing for "a while," per Lerner. A timetable for Urquidy's return has yet to be established, though it sounds as though he'll need longer than the 15-day minimum.
