Kerryon Johnson was a second-round pick in the 2018 NFL Draft, but his career lasted just four seasons and was plagued by injuries.

The former Detroit Lion showed promise in his rookie season, rushing for 641 yards in 10 games, but injuries derailed him for the rest of his career.

He blamed one person for those injuries: his former head coach.

Johnson seemed to be talking about Matt Patricia, who was the Lions’ head coach from 2018 to 2020 before returning to the New England Patriots, joining a list of players criticizing him.

Johnson played in 16 games just once in his four seasons. His fourth season was when he played only one game.
