Tray Walker, a 23-year-old cornerback with the Baltimore Ravens, died Friday from injuries suffered in a traffic accident in Miami, his agent Ron Butler said.

Walker was riding a dirt bike on a Miami road Thursday night when he collided with a Ford SUV driven by a 62-year-old woman.

He was hospitalized in critical condition.

Witnesses said Walker was riding in the dark without a light on, according to Miami-Dade Police. The investigation into the accident is ongoing and no charges have been filed, authorities said.

Walker, who played football at Miami Northwestern High School, played in eight games during the 2015 season. The former Texas Southern University star was a fourth-round pick in the draft last year.

“Tray was a young man with a good and kind heart. He was humble and loved everything about being part of the Ravens’ team,” Ravens head coach John Harbaugh said. “He loved his teammates, the practice and the preparation, and that showed every day. He was coachable, did his most to improve and worked to become the best.”

Ravens owner Steve Bisciotti sent his condolences to Walker’s family.

“We have two sons not too much older than Tray, and we can’t imagine how much his family is suffering,” he said. “This is so sad. The right words are hard to find at a time like this.”

The NFL’s commissioner, Roger Goodell, described it as a “sad day for everyone” in the league.

“The loss of this young man is a terrible tragedy,” he said. “Our thoughts are with Tray’s family and friends.”
