The Omaha Storm Chasers, a Minor League Baseball team for the Kansas City Royals, just announced a special Boba Fett jersey for their May 5th Star Wars Night game against the Redbirds.
The players and coaches will wear the jerseys, which will later be auctioned off that evening to benefit The Methodist Hospital Foundation.
Several professional sports teams have done things like this before, such as the Bradenton Marauders (MiLB team for the Pittsburgh Pirates) in 2014. It's also common that the 501st will have cosplayers before the game begins for some great photo ops.
