New Kids on the Block singer Jonathan Knight revealed that he suffered an injury on the group's tour bus, and as a result, could not perform in Saturday's Los Angeles show.

"Sorry I won't be on stage tonight," he said. "Had an accident on the bus. Banged up my face badly, broke my nose and got a few stitches #fightclub," he shared of the incident.

NKOTB, TLC and Nelly are performing around the country in support of their Main Event tour, which is scheduled to head to San Diego, Calif., on Monday and Glendale, Ariz., on Tuesday, according to SFGate.com.

The 46-year-old tried to make light of the situation and smiled in a selfie he posted on his Instagram, which showed his bruised cheek, busted lip and bloody nose.

".......meanwhile back stage!" he captioned the picture.

Knight's rep said that the singer would keep fans updated by posting on social media to give a specific timeline of when he could be expected to return to the stage.
