yeah missing ACL's are usually not painful and tons of people have rolled without one. Bill Cooper didn't have one for years and just recently got his fixed. Make sure your Dr. knows how serious your interest is in combat sports because a normal coach potato really doesn't need one. If your super serous about jiu-jitsu, consider telling your Dr. it is one of your jobs. That might change his perspective. But yeah, you don't have to have one to be successful in BJJ...
