"We just kept working on them. We said, 'Hey, we're a charter franchise. We're the only team celebrating its 100-year anniversary, and this will be for one year only.' It took some doing. We wore them down a little bit. They finally said, 'OK, for 2019 only.'"

Trubisky also needed to be convinced it was a good idea, but now he's fully on board.

"I'm pretty pumped that I'm going to be wearing '110' this year," Trubisky said. "We're just going to roll and everyone's going to be sporting the nice '1' in front of their jersey number."

It is believed that the only other sport in North America to employ triple-digit jerseys is LigaMX, Mexico's first-division soccer league. All LigaMX organizations field teams in the major league as well as U-20, U-17, U-15 and U-13 leagues. Every player throughout each system is required to have a different number, which is why triple digits are utilized.

The Bears will wear their triple-digit numbers on their navy, white and alternate jerseys this season. Fans will eventually be able to preorder the jerseys from the Chicago Bears Pro Shop. Details will be provided on ChicagoBears.com when they are finalized.
