Travis Roy, the Boston University hockey player who was paralyzed 11 seconds into his first college shift and went on to be a motivational speaker and advocate for spinal chord injury survivors, has died. He was 45.

His death was confirmed by the BU athletic department and the Travis Roy Foundation.

“It is with heavy hearts that we mourn the passing of Travis Roy,” the school said in a post on Facebook. “His story is the epitome of inspiration and courage, and he was a role model and a hero to so many people. His legacy will last forever, not just within the Boston University community, but with the countless lives, he has impacted across the country."

Roy was a 20-year-old freshman making his debut for the reigning NCAA champions in the 1995-96 season opener when he crashed headfirst into the boards after checking a North Dakota opponent.

The accident left him a quadriplegic.

From his wheelchair, he gave as many as 40 motivational speeches a year. The message he shared: Do the best with what you have and don’t dwell on your misfortune.

“I like to say the first 20 years I had a life that was full of passion and the last 20 I’ve had a life full of purpose,” he said in an interview with The Associated Press shortly after turning 40. “The dream is to have both at the same time, but I’m fortunate. I’ll take either one.”

In 1997, Roy created the Travis Roy Foundation, which has raised more than $9 million — half for research, and half to provide equipment for those with spinal chord injuries. Roy, who was able to control the joystick that maneuvered his chair, regained little movement after the injury and had no feeling below the middle of his chest.

“I just thought the research would move along and by the time I was 40 I might have a chance of some normalcy again,” Roy told the AP in 2015, “some kids and a wife and not living with 24-hour home care anymore.”

The hockey world shared its condolences Thursday.

“Travis Roy was the ultimate symbol of determination and courage,” former Boston Bruins star and current team president Cam Neely said. “The impact that Travis had on the New England hockey community is immeasurable, and his relentless advocacy for spinal cord research was inspiring.”

Ray Bourque, another ex-Bruin and Hockey Hall of Famer, said he and his wife were “honored to have known such a great man who helped so many others. Our family sends our heartfelt condolences to the Roy family and everyone Travis touched.”

Also mourning Roy's death was Jack Jablonski, a Minnesota high school hockey star who was also left paralyzed after a hockey collision.

“Travis Roy, you were my friend, mentor, role model and the most positive person I knew,” Jablonski, who was born the week of Roy's injury, said on Twitter. “You have forever changed the SCI and hockey community. Thank you for taking the time to get to know each other. U r my hero. RIP Travis.”

The son of a Maine hockey rink manager who began skating when he was 20 months old, Roy went to North Yarmouth Academy and Tabor Academy before enrolling at BU. Both high schools have named their rinks after him.

BU retired his No. 24 in 1999; he graduated from the school with a degree in communications the next spring.

“I think all the time how grateful I am,” Roy told the AP five years ago. “The thing that goes through my mind every once in a while is, ‘Thank God it wasn’t a brain injury.’ I don’t want any pity.”

Among the players on the 1995-96 BU Terriers team were future NHLers Chris Drury, Jay Pandolfo, Shawn Bates and Mike Grier. John Hynes is now the coach of the Nashville Predators. Coach Jack Parker is an inductee in the U.S. Hockey Hall of Fame; Olympic hero Mike Eruzione was an assistant coach.

Roy said he occasionally thought about what might have happened if he hadn't been injured.

“There’s times when it’s kind of fun to think about it,” he said. “It’s also kind of sad to not know the answer."
