A former CFL player is being hailed a hero after preventing a potential shooting at a high school in Jacksonville, Fla.

Lin-J Shell, a defensive back who won the Grey Cup with the Calgary Stampeders in 2014 and had stints with the Toronto Argonauts, BC Lions, and Winnipeg Blue Bombers, disarmed a woman who brought a gun inside Jean Ribault High School on Wednesday. Shell teaches physical education at the school.

"I just did what I hope someone would do for my son," Shell, 36, told Ryan Rumbolt of Postmedia. "I love all my students, every one of them."

Shell said a brawl broke out in the gymnasium after an "irate parent," upset about a social media feud between her nephew and another student, showed up at the school with several men. The woman, identified by police as 43-year-old Sharon Kelly, allegedly had a small black handgun, which she pulled out as she entered the brawl.

"I walked behind her and I noticed I could see the rear sights of the gun. So I grabbed her wrist and grabbed her elbow and locked her arm down, saying, 'Please don't shoot the kids, please don't shoot the kids,'" Shell said.

He was able to restrain the woman and kept the gun pointed toward the floor while waiting for help. Shell insists he was only doing what he believed was right at that moment.

"I'm not a hero, man," he said. "I'm just a guy."
