Just heard on 1460TheFan that Mack did not actually suffer a herpes outbreak, rub off a cold sore, or chew through his upper lip in the first half. A reporter in Austin mentioned that at one point in the second quarter, Mack was so upset with Colt McCoy that he grabbed McCoy by the facemask as Colt came over to the sideline and pulled him so forcefully that Mack cut his upper lip on Colt's mask.
I never saw that on the TV broadcast ...
