Backstreet's Kevin Richardson was a no-show at the group's concert in Denver this week.

The Backstreet Boy was unable to join group mates A.J., Howie, Brian, and Nick on Tuesday (Feb. 20) because of flight problems.

According to Mitch Schneider, the group's publicist, weather problems delayed Kevin's plane and made it impossible for him to get to Denver in time for the show.

"Richardson had returned to his Los Angeles home on Monday [Feb. 19] for a photo session and planned to join the Backstreet Boys for tonight's show on the Black & Blue World Tour," read the statement. "Richardson's bandmates Nick Carter, Howie Dorough, Brian Littrell, and A.J. McLean performed the show without Richardson, because fans were already arriving to the venue when they learned that Kevin was unable to get there on time."

Fans planning to see the Backstreet Boys in Vancouver on Friday (Feb. 23) will see Kevin meet up with the rest of Backstreet onstage.
