when i broke mine last year it was 4-6 weeks.
then i had a super bad sprain this year felt like it was broken except it wasn't burning
and the doc told me to take the whole season off i didn't and it fixed itself....?
if his ankle is broken, he WILL be screaming, MY ANKLES ARE BROKEN!!! ive broken my ankle once had 2 surgerys, and spend 5 months on crutches, but yeah he would defiantly know if it was broken, he may have sprained it or just rolled it.
