most helpful answer a release to "return to sports" will need come from your medical provider -- the one that examined you for your injury. healing time is so very individual that it would be impossible to blindly determine when you can play sports again since i cannot examine your fingers to see if they are healed. as much as i would like to help you with your question this is not something that can be done over the internet.
how long before i can i return to sports like the one that injured my finger in the first place? . my middle and ring fingers got caught in the elastic waste band of my opponents shorts as i pulled their flag. both fingers injured but i felt a "pop" in my middle finger. i squeezed the middle finger from the top and bottom and felt something move and the discomfort decreased a great deal but on day 3 after injury and wearing a splint i no longer have range of motion whereas i did have full motion on the day of injury.
