Kevin Stefanski: Deshaun Watson was medically cleared, but he didn't feel he could go
Browns quarterback Deshaun Watson was the one who made the decision not to play on Sunday.
Asked if Watson was medically cleared to play in Sunday's loss to the Ravens, Browns head coach Kevin Stefanski answered, “Yes."
So why didn't Watson play? Stefanski said Watson didn't believe his injured shoulder was ready.
