Thank you for the follow up answers, much appreciated.

I will stop stretching totally until 12 weeks from the date of the injury, and avoid any exercise that causes pain or discomfort to the knee. After 12 weeks from the date of the initial injury, I will resume Brazilian Jiu Jitsu sparring with the knowledge that it might be a year until the discomfort stops. At the 12 week date I'll start stretching again, but continue to avoid those stretches (like the photos I sent) that put the most lateral pressure on the knee until a later date. I'll revert back with feedback.

Thanks for the advice.
