Former NFL quarterback Ron Jaworski believes that Robert Griffin III's throwing mechanics prove he is not fully fit yet.
Griffin returned to the field against the Philadelphia Eagles for the first time since he tore his ACL and MCL in his side's playoff loss to the Seattle Seahawks in January and put in a sub-standard performance in their defeat at FedEx Field.
"His mechanics are flawed right now because of the injury," Jaworski told ESPN. "He never gets his weight on the back foot.
"As this ball comes out, it's going to lack energy is front foot, which is where your weight should transfer to, actually pulls back.
"So you're losing the body momentum, the ability to drive the ball with the hip snap, to get the ball to the outside."
Washington face the Green Bay Packers on Sunday.
