Hamstring and treatment

Hey ive torn my hamstring a week out from my teams local aussie rules grand final, and been told by physios the only chance of playing would be if it was 3 weeks away.

However i have heard of cortisone and taping allowing players to particapte, even players contuning to participate after slightly tearing a hamstring so is there anything i can do?

I dont really care bout longer term effects or increasing the injury, all i care about is playing the game and contributing for 2 hours on the weekend.
