Diamondbacks right-hander Daniel Hudson underwent surgery Monday to fix a UCL injury, and according to his twitter account, things went well.
Daniel is out of surgery and resting up for the long road ahead. Surgery went beautifully! Thanks to y'all for your thoughts and prayers!— Daniel Hudson (@DHuddy41) July 9, 2012
We still don't know the extent of the damage in Hudson's elbow or how long he will be out, but the standard recovery from Tommy John surgery takes at least least one year.
Hudson has not pitched since June 26. Though he struggled this season to the tune of a 3-2 record and 7.35 ERA, his loss is one the D-backs are still trying to overcome.
