Finger got pulled back and it hurts?

I had the same exact thing happen to me but it got pulled back by a basket ball. It is just sprained and it will heal. But unfortunately it will take 5-12 days for it to heal. I think you should not play the game because you can make it worse by always having constant movement on your sprained finger. I did not immobilize it but if it feels comfortable, tape the index finger to your middle finger, giving it support, then maybe you can play, a little.
