Padilla, on the disabled list since April 23, has been throwing regular bullpen sessions, however he has felt some minor sensation lower in the arm that club medics believe is from therapy and not part of the original injury. He only began throwing breaking balls off a mound earlier this week.
If the simulated game goes well, Padilla might next try a Minor League rehab assignment. He'll probably need to make three starts in the Minors before he's ready to return to the Dodgers rotation.
Left-hander George Sherrill, placed on the DL on Tuesday with a stiff mid-back he suffered while getting into bed, also might throw an inning in the simulated game. He is also certain to go on a Minor League rehab assignment soon.
