Rangers' Yadiel Rivera: Undergoes elbow surgery

Rivera underwent surgery on his elbow, Jeff Wilson of the Fort Worth Star-Telegram reports.

Per Wilson, the procedure was similar to Tommy John surgery, but involved using an artificial brace rather than a human tendon. Fellow Ranger Danny Santana had the same surgery Sept. 9 and is expected to take eight months to recover, so a similar timeline could be in store for Rivera.
