According to CNN affiliate KCBS/KCAL, Harris was diagnosed with ovarian cancer when she was 18.
"I had a tumor inside of my stomach," she said in 2017. She beat cancer, the station reported.
She said people try all the time to talk her out of playing football and one said she couldn't move from high school football to college.
"I had a coach tell me before that I would never get to the next level because I was a lot smaller and not as fast as the other guys, so that moment taught me to never give up," she told CNN. "From that moment then I told myself no one's ever going to decide what I am going to do with my life. That's my decision."
Last year, Harris, who is 5-foot-5 and 135 pounds, played three games as a sophomore for East Los Angeles College, and had three tackles and one pass breakup, according to the football team's website. Her team went 4-6.
Central Methodist also went 4-6.
"As a coach, giving someone the opportunity to go to college and assist them in getting a degree, that's what it's all about," head coach David Calloway said of Harris, who the school lists at 5-foot-7.
ESPN reported that kicker Rebecca Longo in 2017 signed a scholarship letter of intent to play at Adams State University, an NCAA Division II school in Colorado. Division II schools give partial scholarships to most players.
Longo, who redshirted during the 2017 season, did not appear in a game last year.
Another defensive player, Shelby Osborne, played at NAIA Campbellsville University in Kentucky on a partial scholarship, ESPN reported. According to the school's website, she played in one game in the 2018 season.
