Patrick Mahomes’ Half-Brother Gets a Shot—Will He Make the Final Roster?

The Kansas City Chiefs have extended a rookie minicamp invitation to Graham Walker, the half-brother of superstar quarterback Patrick Mahomes, providing him with an opportunity to earn a spot on the team’s preseason roster. Walker, a tight end who recently played at Rice University, is among the undrafted free agents vying for a chance to shine following the 2025 NFL Draft.

Walker’s journey to this point has been marked by versatility and resilience. Initially an All-American wide receiver at Brown University, he transitioned to tight end after transferring to Rice. At Brown, he totaled 127 receptions, 1,496 yards, and 15 touchdowns over three seasons. At Rice, Walker registered 24 receptions for 252 yards, showcasing his potential and earning praise for his route-running and hands .

Standing at 6-foot-3 and weighing between 215–230 pounds, Walker possesses the size and skills for both wide receiver and tight end positions, describing himself as a tight end with receiver abilities . His athleticism and playmaking ability caught the attention of NFL scouts, despite going undrafted.

Patrick Mahomes has been a vocal supporter of his half-brother, offering encouragement throughout his college career. The Chiefs’ decision to invite Walker to minicamp adds an intriguing storyline to their offseason, as the possibility of the brothers teaming up on the field captures fans’ imaginations.

The Chiefs, coming off a Super Bowl loss to the Philadelphia Eagles, are focused on bolstering their roster to support Mahomes, who remains the cornerstone of their championship aspirations. While the team has made significant moves in the draft, including selecting offensive lineman Josh Simmons to protect Mahomes, the addition of Walker represents a low-risk, high-reward opportunity. His positional flexibility could make him a valuable asset in Andy Reid’s creative offensive schemes.

Walker’s minicamp tryout is far from a guaranteed roster spot, as he’ll compete against other talented hopefuls. However, the chance to catch passes from his half-brother, one of the NFL’s elite quarterbacks, adds extra motivation. As the Chiefs prepare for the 2025 season, all eyes will be on whether Walker can turn this family connection into a professional triumph.
