Urquidy (shoulder) will begin a rehab assignment with the Astros' rookie-level Florida Complex League affiliate Thursday, Danielle Lerner of the Houston Chronicle reports.
Urquidy tossed 34 pitches across a two-inning simulated game last weekend, and he'll now begin the final step in his recovery process. The right-hander will require several rehab appearances to build back up since he's been sidelined since June 29, but he's expected to return from the injured list sometime in September.
