Dak Prescott and girlfriend Sarah Jane dazzle together at Celebrity Fight Night red carpet in Phoenix

Dallas Cowboys quarterback Dak Prescott is a big advocate for fighting the battle against cancer. The 30-year-old lost his mom, Peggy, after her battle with cancer while he was at Mississippi State.

On Saturday night, Prescott and his girlfriend Sarah Jane Ramos attended the 30th Annual "Celebrity Fight Night" at the Fairmont Scottsdale Princess Resort. The event raises money for cancer research.

The Cowboys' quarterback shared a photo of him and Sarah Jane arriving at the event on his Instagram story.
