Mike Shanahan has confirmed that the Washington Redskins will be preparing Kirk Cousins to lead the side during the off-season.
The Redskins head coach told NFL Network: "Kirk Cousins will work at the quarterback position. He'll have all the reps in the off-season.
"Robert will have a lot of reps, but it will be mental. You'll know when he's 100%. What he can do on the football field, what he can do through practices, and he will not come back until he's 100%.
"Robert will do it the right way and we'll find out in July exactly where he's at. You're hoping he's ready, but you can't plan for him to be ready."
Cousins deputised for Griffin when he initially injured his knee in December, leading the Redskins to a win over the Cleveland Browns.
