Britton was placed on the 60-day injured list with left shoulder fatigue Saturday.
Britton was removed from Friday's relief appearance due to his shoulder issue, and the injury will force him to miss the remainder of the regular season and the entire postseason. The southpaw made just three major-league appearances in 2022 and allowed a run on a hit and six walks while striking out one in two-thirds of an inning. Jacob Barnes' contract was selected to take Britton's place in the bullpen.
