The ankle was broken.
Not twisted, not sprained, broken. More, it was one of those breaks that would bench him for weeks.

A growl rumbled through the woods and Sam froze. After a long moment, he heard someone, some thing, shuffling away from his position and he relaxed.
After a quick glance up at the stars, he used a nearby tree stump to pull himself up, then looked around for something to use as a crutch.
Dean would come.
All he had to do was stay alive until the sun came up.
