There is no specific answer for everyone, it depends on how bad the sprain was. There should be a gradual return to your sport. I would recommend staying off your foot completely if there is pain. Then, once you can stand/walk pain free, start walking on it again. Your chiropractor, physiotherapist or medical doctor should provide range of motion exercises and isometric strengthening exercises you can do to speed this transition. Slowly increase the amount of activity you are doing, and always stop when there is pain. Dont start jumping or landing or running on your foot until you can do so with NO PAIN.
You should get specific advice from whatever health care professional is managing your case.
