A 2015 fourth-round pick who played his college ball at Texas Southern University, Walker appeared in eight games with the Ravens as a rookie. Over the course of those appearances, Walker notched two tackles.
According to Ryan Mink of the team's official website, Walker was on the 53-man roster for the entire 2015 season even though he was active just eight times.
"We still hold a lot of promise for Tray," Ravens general manager Ozzie Newsome said at his season-ending press conference, per Mink.
