Shelby Miller's MRI is being sent to Dr. James Andrews for a third opinion.
Miller was asked directly if the first two readings of his MRI showed a torn ulnar collateral ligament.
"They see something in there," Miller said to reporters. "They haven't given me specifics yet, exactly what it is or how we're going to handle it or what we're going to do to fix it."
The Arizona Diamondbacks have downplayed the injury thus far.
"It's part of the plan that we had talked about all along where we were going to have this group look at it and come together and get as much information as we possibly could, and pass it along to Shelby and figure out what the best game plan is," Torey Lovullo said.
