Antwan was diagnosed with the rare blood disorder aplastic anemia in high school. He continued to play football until 2016 when his rare disease diagnosis took a turn for the worse. Forced to leave Kent State University, Antwan was in-and-out of the hospital, went without solid food for two months and dropped to only 125 pounds. He received a life-saving bone marrow transplant from his father in 2017 and started on the road to recovery.
Antwan returned to school in early 2018 and, prior to the start of the season, was cleared by four doctors to start playing football again after nearly 36 months away from the game. He appeared in every game his final two seasons at Kent State and caught a touchdown pass his first game back.
The native of Florida started the Kent State Chapter of Uplifting Athletes and oversaw the Golden Flashes inaugural Lift For Life event as the Chapter President. Antwan was the Mayo Clinic 2018 Comeback Player of the Year.
