I am the world's least coordinated person, which means that playing football of any sort is a bad idea. I jumped up to bat a pass down, and landed funny on my right ankle. I have a pair of crutches, an ace bandage, and 800 mg Motrin (the navy's miracle cure-all) to tide me over. The doctor told me to stay off it for the next week or so. It was apparently a mild sprain, since it's not a longer term.
