Baltimore Ravens cornerback Tray Walker died on Friday after being critically injured in a dirt bike accident on Thursday night, Walker's agent, Ron Butler, confirmed to ET. The NFL star was 23.
"We are grieving the loss of a special young man. #RIPTrayWalker," the Ravens team account tweeted, along with a photo of the young defensive star.
According to ESPN, Walker was riding his dirt bike in Liberty, Florida, on Thursday night, when he collided with a Ford Escape around 7:50 p.m. The Miami-Dade Police Department said that Walker's bike did not have lights and he was wearing dark clothing. Butler told ESPN that the athlete was not wearing a helmet.
Ravens coach John Harbaugh shared an open letter with his team on Thursday -- when Walker was in critical condition at Jackson Memorial Hospital in Miami, Florida -- in which he wrote about receiving "the kind of phone call you never want get as a coach, as a parent, as a brother, as a friend. This shook me and all of us."
"I am asking you to consider what is at stake in your life," Harbaugh wrote to his team. "Consider what your thoughts, actions and choices mean to those around you. Live your life fully and with purpose...Let's look out for one another. Be a great brother and friend."
Ravens wide receiver Steve Smith Sr., as well as many of Walker's Baltimore teammates, shared messages to Walker's family and fans on Twitter.
"A mother lost her son today and a family lost their brother," Smith wrote. "We are the family #Ravennation God rest his soul #traywalker."
