The death of former Redskins linebacker Adrian Robinson has been ruled a suicide, the Philadelphia Medical Examiner's Office told PennLive.com.
Robinson passed away on Saturday night in Philadelphia.
He played brief stints with six teams during his NFL career, beginning as an undrafted free agent with the Pittsburgh Steelers in 2012. He also worked his way onto the roster in Philadelphia, Denver, San Diego, Washington, and Tampa Bay.
The Redskins signed Robinson in Dec. 2013 but he did not appear in a regular-season game with the team before being waived in Aug. 2014.
Robinson was a standout at the collegiate level for the Temple Owls, registering 156 tackles and 22.5 sacks in 50 career games. In 2009, he was named the MAC Defensive Player of the Year.
Former Redskins linebacker Brian Orakpo tweeted the following message on Sunday evening:
"Wow just got word my former teammate from last year Adrian Robinson passed away earlier today," he wrote. "A great young kid w/tremendous talent. RIP AR."
