Colts quarterback Anthony Richardson aggravated the AC joint in his right shoulder and will not participate in next week’s minicamp, head coach Shane Steichen announced Thursday.

Richardson reported soreness and will rest his ailing shoulder, the same one that required AC joint surgery in 2023.

Surgery is not anticipated this time around, per Steichen, who said the plan is for Richardson to return “at some point” in training camp.

“Doctors, trainers checked it out,” Steichen explained. “He’s got some aggravation in his AC joint. So we’re gonna sit him out this week. Obviously, he’ll sit out for minicamp. We’ll see when he comes back. Not gonna put a timetable for training camp on it, but when he does come back, we’ll ease him into throwing, and then we’ll go from there. The good thing is he’s not gonna need a procedure right now.”

Richardson, the fourth overall pick of the 2023 NFL Draft, is expected to battle Daniel Jones for the Colts’ starting quarterback job this season.

“Obviously, it’s frustrating, but he is in good spirits,” Steichen said. “So we’re working through it right now.”

Richardson, 23, enters his third season with 15 starts under his belt (8-7 record), a 50.6 completion percentage, 11 touchdown passes, 10 rushing touchdowns, 13 interceptions and 12 fumbles (four lost).

He completed 47.7 percent of his passes in 2024, historically bad from an accuracy perspective and easily the worst among NFL starters. He had 10 or fewer completions in six of the 11 games he appeared in last season.
