Reds Manager David Bell told reporters that Warren has right elbow surgery to repair his UCL in his right elbow.
Warren was optioned to Triple-A on September 9 but hadn’t appeared in a game since then. The 29-year-old had dealt with forearm soreness off and on through the 2022 season but this news is a bit of a shock. There is no timetable for when he will be able to throw off a mound for the team. It a bit of positive news, the surgery was not a Tommy John surgery, so he could return sometime next year.
