Urquidy (shoulder) will throw a bullpen session at Minute Maid Park on Sunday, Chandler Rome of the Houston Chronicle reports.
Urquidy began a rehab assignment with the Florida Complex League affiliate Thursday, and he allowed a hit and no walks while striking out six in three scoreless innings. His bullpen session will allow the major-league staff to see his progress before he joins Triple-A Sugar Land to continue his rehab assignment afterward.
