Ravens rookie cornerback Tray Walker has passed away after a traffic collision in Miami on Thursday evening. Ian Rapoport and many other NFL players and coaches have been lighting up Twitter with messages of sadness and condolences for the family of the 23 year old corner. In what so far appears to have been an unfortunate accident, Walker was riding a Honda dirt bike in Miami, and was struck at an intersection by a passing Ford Escape SUV. There are conflicting details with regards to the nature of the incident, with Walker’s sister Shalonda Martin claiming that the Ford ran a stop sign. It appears that Walker was operating the bike without lights, and was wearing dark clothing, so that could have influenced the other vehicle’s ability to see him travelling at speed. The driver of the other vehicle stayed on site, and co-operated with attending law enforcement. It appears that Walker was operating the vehicle without a helmet (legal in the state of Miami), which may have exacerbated the level of injury that he received upon impact. He was declared in critical condition at the scene and immediately rushed into surgery with head injuries. There are reports that a New England Patriots player has been listed as a potential witness to the incident, but this is as of yet unconfirmed. Walker was drafted last year from Texas Southern, during the 4th round of the pick, and racked up two tackles over 5 games during his rookie season for Baltimore. The thoughts and prayers of the RealSport writing staff are Walker’s family.
