I think Big Mike had a low invasive laparascopy done to remove the infected appendix. Basically a couple of tiny incisions in the skin of the abdomen then snake in a cable camera and work with small surgical tools to remove the appendix.
I understand that while they were inserting the camera lower belly right side they took the scenic route and came across bacon strips hanging over intestines and a triple cheeseburger that somehow made its way out of the stomach and wedged itself comfortably in the cecum, a pouch connected on the large intestine which is around the corner to the colon. Holy Hopping Gizzards.
On a serious note, this is a good way for Big Mike to be back on the sidelines in a couple of days.
