Mac...don't push it if your ankle is aggrevating you. Getting some squats in will be the least of your worries if the injury happens again. Just go in there and lift what you can lift, when you can lift it.
If you find that you can't squat effectively, then replace squats with quad extensions and hamstring curls (provided those don't aggrevate anything). Members on the site probably already have there crosshairs on my head for saying that
but HST is about size and you can use that substitution to keep the size and gain a bit on your legs.
