Sorry for the bad luck. I hope your finger heals up soon & you get back on the trails. When I was eight years old I was riding my bike barefooted & got my middle toe caught between the chain & crank but I didnt have freewheel on my bike. I had to peddle the rest of the way to get my foot out. I guess the doctor said there wasnt enough tendon there to sew it back on so he cut the rest of it off. I have been living with nine toes ever since. LOL…but its never slowed me down. Good luck with the recovery!
