Rangers pitcher Martin Perez was believed to have avoided a tear in his UCL after an MRI Monday, but after some of the inflammation in the elbow subsided, it revealed a partial tear of the UCL, the Dallas Morning News reports.
Perez and the team haven't decided on a course of recovery yet. One option is to rehab without surgery, with the hope that he'll be able to return in 10 to 12 weeks. The other option is Tommy John surgery, which would sidelined Perez for the remainder of the season and part of next season.
