Not even a ticket could get Butler's bulldog into the NCAA men's basketball tournament in Milwaukee.

Butler University may be playing in Saturday night's second round against Middle Tennessee State at the BMO Harris Bradley Center, but the school's live mascot, a 5-year-old, 65-pound English bulldog named Butler Blue III, will be sitting this game out.

NCAA rules prohibit live mascots from making appearances during the early rounds of the tournament. If Butler gets to the Final Four, the school can petition to have the dog attend the festivities.

But never fear, Blue III, also known as Trip, is in town doing what he does best, charming kids and adults alike while making appearances on behalf of the Indianapolis-based school.

Like the Milwaukee Brewers unofficial mascot, Hank the Dog, Butler Blue is something of a marketing phenomenon, with a line of merchandise that includes hats, plush toy, shirts, even a children's book. He has thousands of followers on Twitter, Facebook and Instagram.

Blue III has even appeared at birthday parties and a wedding.
