Chiefs signed Wyoming TE John Michael Gyllenborg.

25 April 2026

A strong athlete coming out of Wyoming, Gyllenborg (6’6/249) is a solid receiver with room to grow as a blocker. He dealt with injuries in his final two seasons, with a 30/425/3 receiving line in 2024 and a 24/217/1 line in 2025. Gyllenborg initially played basketball in high school and had limited football experience, but his size and athletic traits led to recruiting interest from colleges. As a raw late-bloomer for football, Gyllenborg’s 4.60 40-yard dash and large frame give him the athletic profile NFL teams like to bet on. He will need to be developed further as an inline blocker in order to provide more to a tight end room beyond speed and ball skills in the passing game. Gyllenborg’s athletic upside will give him a chance to make the Chiefs’ roster.
