During a Saturday matinee performance of the Broadway revival of the 1968 off-Broadway hit The Boys in the Bandcast member Jim Parsons tripped causing a cancellation of the evening show.

According to the Associated Press and tweets from those attending the show, Parsons tripped during the encore. While his castmates took their bows, he limped off the stage.

The official Boys in the Band Twitter account made the announcement of the cancellation after the performance.

“Due to a minor injury of a cast member, the Sat evening performance has been canceled,” they announced. “Performances will resume Monday night.”

The Boys In The Band takes place at an alcohol-fueled birthday party for a gay man and his friends that turns inexorably – and with acid humor – from celebratory to toxic as relationships unravel, feelings are shredded and alliances are food-processed. In addition to the Emmy Award-winning Parsons, the 50th anniversary of the groundbreaking production also stars Zachary Quinto, Matt Bomer, Andrew Rannells, Robin De Jesús, Brian Hutchison, Michael Benjamin Washington, and Tuc Watkins.
