Brandon Williamson: Everything you need to know

The Reds transferred Williamson (shoulder) from the 15-day injured list to the 60-day IL on Wednesday. The transaction clears space on the 40-man roster for the addition of Tejay Antone, who was called up from Triple-A Louisville. Williamson landed on the 15-day IL last week with left shoulder fatigue and now won't be eligible for activation until late June.

The Reds placed Williamson on the 15-day injured list Thursday due to left shoulder fatigue. Williamson was removed from his start in Wednesday's 13-2 loss to the Rockies with the issue. Manager Terry Francona said Thursday that Williamson doesn't have structural damage to his shoulder and will resume a throwing program after being given a cortisone shot, per Charlie Goldsmith of Fox 19 Now Cincinnati. It's unclear how long the left-hander will be sidelined, but with Nick Lodolo (finger) due back from the IL soon, Williamson could be without a rotation spot once he's ready to return. Williamson holds a 6.11 ERA and 19:20 K:BB over six starts covering 28 innings this season.

Williamson was removed from Wednesday's game against the Rockies with left shoulder fatigue, Charlie Goldsmith of Fox 19 Now Cincinnati reports. Williamson made it through just three innings before coming out of Wednesday's game, giving up four earned runs on four hits and four walks while striking out four batters. It's currently unknown whether the shoulder issue will cause the Reds to postpone his next start or move him to the IL, but he's slated to receive an MRI on Thursday that will help determine his short-term availability.
