Chiefs Add Marcus Harris to Active Roster, Sign Jack Pyburn to Practice Squad

The Kansas City Chiefs signed defensive tackle Marcus Harris to the active roster and defensive end Jack Pyburn to the practice squad Thursday, adding depth along the defensive line ahead of Sunday’s game against the Atlanta Falcons.

Harris had been on the practice squad and received a standard elevation for last Sunday’s game against the New York Jets. This week, he takes a spot on the active roster. Kansas City had waived Pyburn the day before his practice-squad signing, according to the team’s transaction log.

The move gives Kansas City another option inside with Peter Woods unavailable. The Chiefs ruled Woods out with a neck injury after he missed all three practices this week. Defensive tackle Omarr Norman-Lott was limited Friday with a knee injury and was also ruled out, according to the final injury report.

Harris is in his second season with Kansas City. The Houston Texans drafted him out of Auburn in the seventh round in 2024, taking him No. 247 overall, according to his Chiefs player bio. Kansas City waived him at the end of this year’s preseason, then signed him to the practice squad.

Pyburn joined the Chiefs on a waiver claim at the end of August after coming out of LSU. His latest move came during the same week Kansas City acquired wide receiver Josh Downs from Indianapolis. The Chiefs also waived punt returner Nikko Remigio in that round of moves. Pyburn’s practice-squad deal keeps him available if the team needs help at defensive end later in the season.

Inside, the Chiefs are coming off a big game from Chris Jones, who had two sacks in the 35–12 win over the Jets and earned AFC Defensive Player of the Week honors. With Woods and Norman-Lott out, Harris gives Kansas City an extra defensive tackle it can dress against an Atlanta offense led on the ground by Bijan Robinson.

Kansas City enters the game at 6–2, and Atlanta is 3–6. Kickoff is set for 1 p.m. ET at Mercedes-Benz Stadium. Harris’s signing gives the Chiefs the option to use him in the defensive tackle rotation Sunday. The game-day inactive list will show whether he gets that opportunity in Atlanta.
