OwlScoop.com reported Sunday ex-Steelers outside linebacker Adrian Robinson died at the age of 25 early Sunday morning. Cause of his death wasn’t immediately reported.

He was playing with the Hamilton Tiger-Cats of the Canadian Football League. The team announced his death, but didn’t provide any further details.

Robinson, an undrafted free agent of the Steelers out of Temple in 2012. He was on the team’s roster in 2012, but after a year of mostly deactivations, he was traded to the Philadelphia Eagles in exchange for running back Felix Jones during training camp.

While his career wasn’t anything in terms of statistical achievement, Robinson was a glimmer of hope in a bleak future outlook for the Steelers at the position. Like other undrafted and low-round draft picks who went onto prominence with the Steelers at the position, Robinson had the athleticism and the preseason production to endear himself with Steelers fans.

His training camp in 2013 was nowhere near as compelling as it was in 2012, and it was clear the Steelers weren’t going to get more from him. He bounced around the league, spending time with the Chargers, Broncos, Redskins and Buccaneers after being cut by the Eagles in 2013.
