Melody,
if they mean for him to walk or put weight on it, he'd have a heel built into the bottom of the cast. No heel means no weight in my experience and believe me I've had a lot of it. I tore tendons loose from my ankle, they took a tendon from the back of my calf and spliced the tendon in my ankle. No heel, no weight was what I was told. And tell him NOOO coathangers inside it to scratch. (yes it will get itchy) He needs to support his weight on his good leg and the crutches. Yes, it will be difficult. He's a strong man. If I can do it he can, let him do it, don't hurt yourself.

You can call your doctor on Monday to see how much if any weight he can put on it.
