The series of photos was a touching tribute from Jackson Mahomes to his mother. Randi re-shared the photos and added that her younger son made 'her smile' on her birthday with the post.

Does Patrick Mahomes have another brother besides Jackson?

Patrick Mahomes' family is often shown during his Kansas City Chiefs games. His younger brother Jackson is a well-known social media figure and his younger sister Mia is a budding volleyball star.

However, last week, ahead of the Chiefs Wild Card victory over the Miami Dolphins, it was revealed that he also has another younger brother. His father Pat Mahomes Sr. did an interview with FOX 4 Kansas City and mentioned his son Graham. He is Patrick and Jackson's half-brother from their father's side.

When asked to talk more about him, the elder Mahomes said that Graham Walker plays college football at Brown University.

He also said that he entered the transfer portal and is looking to fully concentrate his attention on football moving forward. Walker apparently now has his eyes set on a possible NFL career like his older brother Patrick Mahomes.

Walker is a wide receiver and Mahomes Sr. even said that his sons may work out this upcoming NFL offseason. He also said that his youngest son is a bit more reserved that his older children and tries to stay out of the spotlight. However, his potential NFL career could change all of that.
