Mac has been featured in two mainstream, popular magazines.
Sports illustrated did an in-depth feature on him here: http://www.sportsillustrated.com/2008/writers/ben_fowlkes/05/01/mac.danzig/index.html
And Men's Fitness is featuring him as one of the "25 Fittest Men in America" in the July issue. They have an interview here (first question is about veganism!): http://www.mensfitness.com/fitness/288?page=1
(my favorite question in this interview: "What do you think about the claims that soy protein is estrogenic and will make you grow boobs and cause your balls to fall off?")
and also a "UFC Workout" based on his routine here: http://www.mensfitness.com/fitness/workout_routines/292
Mac's official site, http://www.macdanzig.net
also says that while the fight hasn't been signed yet, Mac's next fight will likely be in September.
