The Indianapolis Colts placed cornerback Charvarius Ward Sr. on injured reserve on Saturday and he will miss at least the next four games.

Ward sustained a concussion during warmups prior to last weekend’s victory over the Arizona Cardinals. He missed the entire week of practices leading up to Sunday’s game against the host Los Angeles Chargers.

The Colts have a bye in Week 11, meaning the earliest Ward can return is the Week 12 road game against the Kansas City Chiefs on Nov. 23.

Ward, 29, has 13 tackles and three passes defensed in four games with Indianapolis this season.

Ward is in his first season with the Colts after playing for the Kansas City Chiefs (2018-22) and San Francisco 49ers (2022-25). Ward was part of the Kansas City squad that won the 2019 season Super Bowl and he also was a member of two teams (2020 Chiefs, 2023 49ers) that lost in the Super Bowl.

He was a Pro Bowl pick and second-team All-Pro in 2023 when he intercepted a career-best five passes and led the NFL with 23 pass breakups.

Indianapolis also signed running back Ameer Abdullah to the 53-man roster from its practice squad. Abdullah, 32, has played in two games earlier this season and carried three times for 13 yards and a touchdown.

The 10-year veteran has 2,007 rushing yards and 20 total touchdowns (nine rushing, 11 receiving) in 143 games with five NFL teams.

His services were needed after running back Tyler Goodson (groin) was ruled out Friday.

The Colts also elevated cornerback Cameron Mitchell and receiver Laquon Treadwell from the practice squad. Cornerback Kenny Moore II (Achilles) is questionable while wideouts Josh Downs (concussion) and Ashton Dulin (chest) were ruled out.
