Colorado placed Herrera on the 15-day injured list Friday due to left elbow inflammation, but he was shifted to the 60-day IL just two days later after a follow-up MRI apparently revealed that the 22-year-old reliever was dealing with ligament damage. Schaeffer said that the Rockies don't currently have a timeline for Herrera to go under the knife, as the left-hander will presumably receive additional medical evaluations before deciding whether to get Tommy John surgery, an internal brace procedure or a hybrid of the two. Even if Herrera avoids a UCL reconstruction and instead has a UCL repair surgery, he's still likely to require close to a full year of rehab and recovery before returning to game action in the middle or second half of the 2027 season.
