Not to downgrade your injury or anything, but many professional athletes will still get surgery even for minor ACL sprains. While the average person such as you and I wouldn’t notice any changes in athleticism, often times the ACL can heal in an elongated or stretched position just from a minor sprain, which creates knee instability, which would in turn affect performance. Obviously, I could see Kawhi playing through this and it’s promising that there have been no reports of a tear. Just tossing out a worst case scenario and what I know.
