Demaryius Thomas, who may be most remembered for 5 Pro Bowl seasons with the Denver Broncos, was found dead in his suburban Atlanta home on Thursday night. He was 33.

Thomas, who was drafted out of Georgia Tech by the Broncos No. 22 overall in 2010, showed enough talent despite being a wide receiver in Paul Johnson’s run-oriented offense. Thomas won a Super Bowl with the Broncos and last played for the New York Jets in 2019 before he retired this past summer.

LaTonya Bonseigneur, a first cousin who grew up with Thomas and was so close they considered themselves siblings, told The Associated Press the family believes he died from a seizure.

Family members were notified by the Roswell police at about 9 p.m. EST that they had found Thomas in a shower at his home.

“He had been suffering from seizures for over a year, and we believe he had a seizure when he was showering,” Bonseigneur said early Friday. “We’re not sure when he died. We just spoke with him yesterday.”

Thomas’ biggest NFL highlight may have been an 80-yard touchdown catch in a 2011 AFC wild-card playoff game, on a pass from Tim Tebow to beat the Pittsburgh Steelers.
