Matthew himself wrote this last night (Thursday evening, California time). He will have the skin graft surgery in about 15 minutes.

"Life update from San Francisco, Ca. I talked to my doctor about my left arm this evening. I am in the right place and have an incredible team. I am accepting that my left arm will never be the same as before my accident. I am in a challenging position and extremely blessed to be alive. Within 2 months we can find out a lot. I am taking the first steps on a long road to recovery. Lord willing tomorrow morning I will have a skin graft surgery. Thank you so much, you are the true meaning of family and friends ❤️"
