Indianapolis Colts quarterback Anthony Richardson will miss “some time” with a sprained AC joint in his right shoulder, coach Shane Steichen confirmed Monday.

The rookie reportedly sustained a Grade 3 sprain during the second quarter of Sunday’s win against the visiting Tennessee Titans.

Steichen said the Colts are still evaluating whether to place Richardson on injured reserve, which would sideline the first-round draft pick for at least the next four games.

ESPN reported that Richardson will seek a second opinion from shoulder specialist Dr. Keith Meister.

Richardson, 21, fell on his right shoulder after being tackled by Titans linebacker Harold Landry III. Richardson, who completed 9 of 12 passes for 98 yards, went to the blue medical tent before going to the locker room. He was replaced by Gardner Minshew.

The fourth overall pick in the 2023 draft out of Florida, Richardson missed Week 3 after sustaining a concussion the previous week against the Houston Texans. He briefly came out of the Colts’ season opener with a lower-body injury late in the loss to the Jacksonville Jaguars.

Minshew went 11-of-14 passing for 155 yards in Indianapolis’ 23-16 victory. Neither Richardson nor Minshew threw a touchdown pass or an interception.

The Colts are tied with the Jaguars at 3-2 atop the AFC South. The teams meet Sunday in Jacksonville.
