Mono was because of his Crohn's disease. Crohn's is an autoimmune disease that keeps your body down. Small wonder it happened to Nance with how busy he is and coming off of knee surgery. We are lucky to even have him this year. Crohn's is nothing to mess with and and when he has an episode, it can open up the door for anything else going around. It is pretty remarkable that Nance is playing at as high of a caliber as he is. Crohn's is a tough disease to have. I have most of the symptoms but got diagnosed with a different one. But I have friends with it and feel for them. It makes me that much prouder of Nance knowing what he is going through. I am sure most on here know someone battling Crohn's.
