The latest suspension marked another blow to the wide receiver’s tumultuous career. Since he entered the league in 2012 with the Cleveland Browns, Gordon has been suspended five times for violating either the league’s substance-abuse policy or its performance-enhancing drug policy.

He had stepped away from the Patriots earlier this season to focus on his mental health.

Gordon has played six seasons in the NFL and had missed two full seasons due to suspension. He has caught 247 passes for 4,252 yards and 20 touchdowns over his career.
