Shelby Miller's forearm injury is worse than the Diamondbacks originally feared.
Miller told reporters Thursday he has a partial tear of his ulnar collateral ligament (UCL) and is considering Tommy John surgery. He is currently on the 10-day disabled list.
The 26-year-old right-hander left his start Sunday against the Dodgers with forearm tightness. Results from an MRI were originally inconclusive, but the MRI was sent yesterday to noted orthopedic surgeon James Andrews for a third opinion.
"I still haven't made a decision on what I'm going to do yet," Miller said, via AZCentral.com. "I'm still kind of processing all of it. It's still kind of early."
Miller is 2-2 this season with a 4.09 ERA, a big improvement from last season's nightmare (3-12, 6.15 ERA).
