The boy band, along with TLC and Nelly, brought their The Main Event tour to the iconic Hollywood landmark The Forum, but the New Kids were down a member after Knight had an incident on their tour bus prior to the gig.

He took to Twitter.com on Saturday to share the disappointing news with fans and wrote, "Sorry I won't be on stage tonight. Banged up my face badly, broke my nose and got a few stitches #FightClub."

He also posted a selfie on Instagram, showing off his badly bruised face, but still managed to crack a smile.

It is not clear whether Knight will miss out on any more performances on the tour, which kicked off 1 May (15) in Las Vegas and is slated to continue through 2 July (15) with stops throughout the U.S. and Canada.
