Daniel Hudson's timeline slows down

For a while, it seemed like Diamondbacks starting pitcher Daniel Hudson was on the fast track to return from Tommy John surgery, as he had managed to avoid any setbacks. That is, until Tuesday, when his rehab debut at Double-A Mobile was cut short due to stiffness in his surgically repaired right elbow.

Despite the setback, manager Kirk Gibson does not seem concerned about his long-term prognosis. He admits that it could delay Hudson's return to the rotation, which looked to be fast approaching prior to Tuesday.

"He was sore," Gibson told MLB.com. "I'm taking an optimistic view on that. He hasn't had any setbacks at all since he's been doing his rehab. I'm confident it'll work out fine. Does this slow him down a little bit? It probably does, yes."

Hudson is scheduled to see Dr. Michael Lee Thursday to determine if there are any structural issues that led to the stiffness in his start.
