This is a big change that the Detroit Pistons and Red Wings have already adopted at the new Little Caesars Arena.

Cue the outrage from people who don't have smartphones - Comerica Park will no longer accept paper or printed-out tickets as an entry to Tigers games.

This all starts tomorrow if you're planning on attending Tigerfest. You have to download the Major League Baseball Ballpark app or the StubHub app, available in the app store or Google Play. An employee will scan the code from the app for your ticket.

If you don't have a smartphone, you can call the Comerica Park box office at 313-471-2200, or visit them prior to your event.
