11:00am: Infielder Enmanuel Valdez also underwent season-ending surgery this week, Tomczyk tells the Pirates beat (via the Post-Gazette’s Colin Beazley). Valdez hit the 10-day injured list due to inflammation in his left (non-throwing) shoulder on May 10. He was moved to the 60-day IL a few days later with minimal updates on his outlook. He’s now expected to be sidelined for roughly six months.

10:52am: Pirates right-hander Jared Jones will undergo season-ending surgery to address his ailing right elbow, senior director of sports medicine Todd Tomczyk announced to the Pirates beat this morning (link via Noah Hiles of the Pittsburgh Post-Gazette).

Jones has been out all season with an elbow injury. Evaluations back in spring training did not lead to a recommendation of surgery, but Jones recently met with Dr. Keith Meister — an orthopedic surgeon who’s performed dozens of Tommy John procedures for MLB players — after his return to throwing in late April seemingly did not go well.

It’s not yet clear what type of surgery will be performed, but since Jones has been dealing with a UCL sprain, Tommy John surgery and an internal brace procedure are both presumably on the table. Jones is going under the knife today, so more information on the nature of the surgery and his timetable for a return should be available within the next few days.

More to come.
