DALLAS (CBSNewYork/AP) — Former Patriots and Cowboys wide receiver Terry Glenn died Monday following a one-vehicle rollover traffic accident near Dallas that left his fiancée slightly hurt, officials said. He was 43.

Glenn died shortly before 1 a.m. at Parkland Memorial Hospital in Dallas, according to the Dallas County Medical Examiners Office. Irving police are investigating the cause of the wreck at 12:18 a.m. on eastbound Highway 114, said Chelsey Jones, a police department spokeswoman.

Glenn, who lived in the Dallas area, was driving when the vehicle left the highway, struck a concrete barrier and rolled, authorities said. Glenn was ejected. Jones said his fiancée was taken to a hospital for treatment of minor injuries. Her name and further details weren’t released. Jones had no immediate information on whether the couple wore seatbelts.

The seventh overall pick in the 1996 draft by New England, Glenn played 12 seasons in the NFL — six with the Patriots, one with the Packers and five with the Cowboys. He had four 1,000-yard seasons, was a Pro Bowl selection with New England in 1999 and was a member of the Patriots’ 2001 Super Bowl champion team.

His final season was 2007.

Glenn played his college football at Ohio State, where in 1995 he won the Fred Biletnikoff Award, given to the nation’s top wide receiver.

Former NFL player Tony Casillas was among the first to report the news of Glenn’s death Monday morning.

“Asking for prayers for Terry Glenn’s family he passed away this morning from car accident prayers for his fiancée,” Casillas, a former Jets defensive tackle, tweeted.

Patriots coach Bill Belichick mourned the loss.

“I was pretty close with Terry,” Belichick said. “His rookie season was my first year here in ’96, so I had a lot of interaction with him and other people that were involved in his life and his upbringing separate from the Patriots. Terry’s a very smart individual. Had, obviously, a lot of physical skill and talent. Could do a lot of things on the football field very naturally. And I think was, deep down inside a good person with good intentions and a good heart. Obviously, it’s a very unfortunate passing and a sad day.”

Former Patriots quarterback Drew Bledsoe expressed his sorrow via social media.

“Loved this man. My son asked me a decade ago who my favorite receiver ever was because he wanted that jersey for Christmas. He got a Terry Glenn jersey from Santa,” Bledsoe wrote. “TG overcame horrible adversity to become a really good man. May your soul rest in peace my friend.”
