ASHBURN, Va. — The Washington Redskins are optimistic that Robert Griffin III will return this season.

An MRI exam on Monday revealed that Griffin doesn’t have any broken bones to go along with his dislocated left ankle, which means he doesn’t need season-ending surgery and could theoretically return in a couple of months if all goes well with his rehab. Kirk Cousins will be the starting quarterback for much — if not all — of the rest of the year.
