The Kansas City Chiefs announced on social media that assistant special teams coach Andy Hill is retiring after five seasons with the team.
Hill was with Kansas City from 2020-2024, working under special teams coordinator Dave Toub. Before joining the Chiefs, Hill spent 24 seasons at the collegiate level with Missouri.
He worked in a variety of different roles with the Tigers, including special teams coordinator, wide receivers coach, quarterbacks coach, and co-offensive coordinator. Hill played WR at Mizzou from 1980-1984.
Per Matt Derrick of Chiefs Digest, replacing Hill will be assistant running backs coach Porter Ellett. Taking Ellett's old position will be Mark DeLeone.
With Andy Hill’s retirement, Porter Ellett has moved to assistant special teams coach for Dave Toub. Mark DeLeone, former linebackers coach for the Chiefs, returns to KC and takes over Ellett’s old role as assistant RB coach.

Ellett is entering his eighth season with the Chiefs. Prior to being the assistant RBs coach, he was an offensive quality control coach from 2020-2022, and was the senior assistant to the head coach from 2017-2019. Ellet completed his undergraduate degree at Brigham Young University, the alma mater of Andy Reid.
This will be DeLeone's second stint in K.C. From 2013-2015, he served as the defensive quality control coach, then moved to assistant linebackers coach in 2016. In 2018 he moved to inside linebackers coach specifically. DeLeone most recently was with the Baltimore Ravens (2024) in the same role.
The Chiefs are continuing their trend of promoting from within and working with coaches who they have familiarity with. Andy Reid has one of the biggest and most successful coaching trees in NFL history, which will keep making an impact around the league for the foreseeable future.
