Rolled Ankle??

So i just rolled my ankle playing in a basketball game. Yea not very much fun. I was supposed to have an 80 minute run and a 45 mile bike run. I can barely walk, and it is really swelled up to the size of an orange about i would say. Yea pretty fat!! What is the best way to keep up my current condition, with out hurting my ankle anymore. I know water workouts are probably the best way to go untill i can start jogging on it? I am afraid that doing a free style all the kicking will end up putting me back So i am thinking about running in the pool or dead leg swimming. I just use my arms and let my feet drag. It wont be good form but i figure for a week, it will at least let me keep my swimming up and hopefully i won't lose too much. Any advice?
