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.”

Walker was taken by the Ravens in the fourth round of the 2015 NFL Draft. He played eight snaps on defense during his rookie season, and registered one tackle.
