Colts waive CB Mekhi Blackmon, add undrafted corner Kenneth Harris

The Indianapolis Colts have waived cornerback Mekhi Blackmon, a move that reshapes their defensive back depth heading into the next phase of the offseason. Pro Football Rumors reported that the team also signed undrafted rookie corner Kenneth Harris in connection with the transaction.

Blackmon’s time with the Colts included meaningful playing time. According to the report, he started 11 games for Indianapolis in 2025, giving the team experience on the outside and in coverage rotations as the regular season progressed.

From a roster-construction standpoint, waiving a player who has started games indicates a reset of the depth chart rather than a minor administrative adjustment. Teams often use the late-summer window to sort out who can handle different coverage responsibilities, play assignment discipline, and special-teams roles, especially when the roster is close to the regular-season limit.

The corresponding addition of Kenneth Harris continues that logic. The report frames Harris as an undrafted rookie corner, a type of signing that typically reflects the Colts’ search for developmental upside and reliability on the practice field, with the possibility that he earns a role if he proves himself in coverage fundamentals and communication.

Individually, Blackmon now faces the waiver wire process. While the report characterizes him as “in limbo,” the practical outcome will depend on whether another team claims him or whether he clears waivers and becomes available through a different roster mechanism.

The Colts’ cornerback room, meanwhile, is now a clearer picture of who the staff prefers going forward. With Blackmon removed, the competition for snaps in base and sub packages becomes more concentrated among the remaining veterans and rookies.

For Colts fans, the next watch item is how Harris fits into the team’s immediate needs. Even if he does not step into a starting role right away, a rookie corner’s early value is often tied to coverage matchups in practice and his willingness to contribute on special teams.
