The Kansas City Chiefs added depth on both sides of the ball this week, signing safety Alohi Gilman, defensive tackle Khyiris Tonga, running back Kenneth Walker III and cornerback Kader Kohou.

Gilman, 28, played in 17 games last season with the Chargers and Ravens, finishing with 90 tackles, nine passes defended and a defensive touchdown. He has experience at multiple spots in the secondary.

Tonga appeared in 14 games for the Patriots last season with eight starts. The 6-foot-2, 335-pound lineman recorded career highs in snaps, pressures and defensive stops while working primarily at nose tackle.

Walker joins the backfield after rushing for 135 yards and earning Super Bowl MVP honors in Super Bowl LX. He has topped 1,000 scrimmage yards in three of his four NFL seasons.

Kohou started 38 games for the Dolphins from 2022-24 before missing last season with a knee injury. The slot corner recorded 28 passes defended during his first three seasons in Miami.
