The Chiefs are keeping it all in the family.

Out of 87 players participating in the team’s rookie minicamp this weekend, 60 are on a tryout basis, and one in particular stands out.

Graham Walker, who is the half-brother of quarterback Patrick Mahomes, will be a part of the camp, according to ArrowheadPride.com.

He is also the son of Patrick Mahomes Sr, but he grew up in Vermont with his mom, Jessamyn Walker, and stepfather, Gerry Howatt.

Walker recently completed his final year as a tight end at Rice University. Before transferring last season, he had spent three years at Brown with the original intention of playing as a receiver.

Following the year, he declared for the draft at 6-foot-3 and 227 pounds but was not selected last week in Green Bay.

In his 2023 season at Brown, Walker had 44 catches for 515 yards and six touchdowns. With Rice, he caught 24 passes for 252 yards and zero touchdowns in 2024.

His best college year came as a freshman, recording 658 yards for six touchdowns in 2021.

It is unknown how Walker and Mahomes define their relationship, but according to the Daily Mail, the two have met a few times.

However, Walker recently admitted his three-time Super Bowl-winning half-brother has been keeping a watchful eye on his game.

“I know Patrick has been watching the games, and he’s reached out and said good things that I’ve been doing,” Walker told Seven Days. “When someone who’s accomplished so much can say you’re doing well, it really feels good.”

With any luck, Walker could find himself in the Chiefs’ tight end room with Travis Kelce.

The camp started on Saturday and is set to run through Monday at the Chiefs’ facility.
