Gavin Floyd to undergo Tommy John surgery

Update: Floyd will indeed have Tommy John surgery on his UCL. His recovery time is expected to be between 14-16 months, which will cause him to miss a good portion of the 2014 season. Floyd is scheduled to become a free agent after this season. It seems likely that he has played his last game in a White Sox uniform.

Original post from May 3:

White Sox starting pitcher Gavin Floyd will likely undergo Tommy John surgery. Floyd was placed on the disabled list April 26 with what was believed to be an elbow flexor strain. Later reports then said that he actually tore the flexor muscle.

The plans to have the surgery are tentative, reports USA Today's Bob Nightengale. Floyd, 30, planned on having multiple medical opinions on his injury. Originally, an MRI did not reveal any structural damage.

Tommy John surgery would end Floyd's season and likely cost him at least the first month of 2014. The typical rehab time for the surgery is about a year.

Floyd had not been pitching well this year prior to his injury. In five starts, he posted a 5.18 ERA and 1.603 WHIP. He was posting a career high 9.2 K/9.

Hector Santiago figures to be in the Chicago rotation full time moving forward. Santiago started the year in the White Sox bullpen, but joined the starting staff Thursday for a spot start while Jake Peavy was scratched due to back spasms.

Santiago gave up just two hits and a run over 5.1 innings against the Rangers during that start.
