A Texas high school football star collapsed and died in his twin brother’s arms after suffering a suspected heart attack, according to reports.

Defensive tackle Deshaud “Dee” Williams, 16, had been playing tag with his twin, Dashaud “Da Da,” in Lewisville on Friday when he suddenly collapsed, according to NBC DFW.

“We started jogging a little bit more and he was like, ‘Da, I can’t breathe,'” the grieving twin told the station through tears.

“I was like, ‘You good? Come on, we’re going to get home.’ And he was like, ‘I can’t breathe. I’m about to pass out.’ And I ran to him and he fell to his knees and fell on his back.”

An ambulance arrived in minutes but the teen was pronounced dead on the way to a hospital, according to a fundraising page to raise money to bring his body back to Cleveland, Ohio, where he was born.

“His heart couldn’t take no more and he died in his brother’s hands,” said his crying mother, Razel Sheppard, insisting her son had recently had a physical with a heart test that raised no concerns.

“He’s never been sick. He was a healthy all-around kid,” she said, calling his death “a big mystery.”

The teen was a defensive tackle on the junior varsity football team at Lewisville High School, where he was also an honor student.

“Today our hearts are broken,” the team tweeted Saturday. “Please keep the Fighting Farmer community in your prayers as we mourn the loss of a student athlete.”
