NFL legend who defied odds off the field has tragically passed away at the early age of 50

Another tragic incident involving an all-too-young former NFL player.

Former NFL standout Dennis Byrd, who had his career ended by a neck injury was killed in a two-vehicle injury Saturday morning in Oklahoma.

A 2000 Ford Explorer driven by a 17-year-old kid reportedly veered into oncoming traffic and collided head-on with Byrd's 2004 Hummer V2, killing him on impact thanks to a variety of injuries, per Tulsa World. A 12-year-old in Byrd's passenger seat was transported in critical condition, as was the 17-year-old driver, via the report.

Byrd overcame a debilitating neck injury, in which he suffered partial paralysis after hitting a teammate in a 1992 game, shattering one of the vertebrae in his neck, per Fox Sports.

He defied doctor's prognosis and was able to walk within months of the injury.

Former coach Pete Carroll shared the story of the collision to Newsday, and discussed the horrifying details:

"He didn't even have the [neck] halo on yet, but we had to all tip him over so he wouldn't choke on his own vomit,'' Carroll said. "It was just horrible. Horrible. Just so catastrophic for a young man's life."

Carroll then said the team officials wanted to tell teammates Byrd would be a quadriplegic. 20 years after that hit, the Newsday piece noted Byrd was able to get around, though with some difficulty, on his own as he tended to a ranch with four kids and his wife.

"His injury was tough on him," former teammate Jerry Ostroski told Tulsa World. "It was hard on him sometimes. He was in a lot of pain. He did a tremendous amount of work to be able to walk again, but he was in a lot of pain and it was hard on him. Over the years as he got a little older it was rougher on him. You didn't see him quite as much."

Our thoughts go out to Byrd's family and friends.
