If you're going to a Detroit Red Wings or Detroit Pistons game at Little Caesars Arena, whoever has your tickets better not forget their phone.

That's because the LCA, which opened a season ago, will no longer accept paper tickets for Wings or Pistons games.

This announcement came during the summer and may have flown under the radar. But now that the NHL and NBA have returned, you need to know that Ticketmaster's mobile ticketing technology will be used at the doors of the new arena.

So the days of printing off tickets at work before heading to the game or cursing the ink gods after you run out at home are long gone.

If you have a smartphone, you can download The District Detroit app to buy your tickets and display.

If you don't have a smartphone, you're not totally out of luck. Simply call the LCA box office (313-471-7929) ahead of time or head over to the the box office on the day of the game to get your tickets.

Full-season ticket holders will receive a commemorative printed ticket to celebrate the upcoming season. Tickets should be loaded into season ticket holders' online Ticketmaster account.
