Ankle injury in rugby, need rehab help??

I was playing rugby for NAU and I tackled one of the opponents and rolled my ankle forward instead of sideways, I heard a small pop, but could still walk on it with a little tendernous, I looked up a number of medical sites and I think i have Dislocation of the peroneal tendons, but the thing is that on the foot when I pull my toes towards me there is a bump that comes out from the right side of my foot and there is still some swelling, I tried to play volleyball the other day after 2 weeks and it became tender again, what do you think it is, and should I cast it up with a walking cast or something, I only have 6 weeks till rugby starts again and I want to play and should I ice it even though it is almost 2 weeks since the original injury.
