The Diamondbacks confirmed Friday that right-hander Daniel Hudson, while rehabbing at Double-A Mobile in hopes of returning to the team soon following elbow ligament surgery last year, re-tore the same ligament during a start earlier this week.

Hudson originally tore the ulnar collateral ligament in his right elbow in a start last July and underwent Tommy John surgery. He rehabbed for about 10 months of and had a brief stint in extended spring training before going to Mobile, where he made his first start Tuesday and apparently re-injured his arm.

The D-backs said they are exploring all options, but it is likely that Hudson will again need Tommy John surgery, which typically requires about a year of recovery time.
