Stephen Strasburg will not make his next scheduled start Thursday and will almost certainly be placed on the disabled list, Nationals manager Jim Riggleman said this afternoon.
Strasburg underwent an MRI of his right forearm yesterday, the results of which are still be looked at by doctors. Team officials won't determine a full course of action moving forward until they receive more information.
Riggleman didn't reveal any initial diagnosis from the MRI but did say this test offered a less-encouraging outlook than the hands-on test administered by a Phillies team doctor Saturday night. That doctor said he believed Strasburg would be fine to pitch Thursday as scheduled.
A decision hasn't been made yet who will start in Strasburg's place, but Riggleman did say rehabbing minor-leaguer Jordan Zimmermann is a possibility.
General manager Mike Rizzo is due to meet with reporters later this afternoon to provide more details, so updates to come...
UPDATE AT 5:55 P.M. -- Mike Rizzo said the MRI taken on Strasburg's forearm showed a strained flexor tendon. He'll now undergo an arthrogram, an enhanced MRI in which a dye is injected in the arm to help doctors better identify any problems, within the next couple of days.
Rizzo said the Nationals won't make a decision on the plan for Strasburg moving forward until the results of the enhanced MRI are diagnosed, though the pitcher will go on the 15-day DL and thus miss at least a couple of starts. Rizzo wouldn't rule out the possibility of Strasburg returning to pitch this season. The rookie reported to the ballpark earlier today hoping to play catch and believed he could start Thursday as scheduled.
