Authorities in Providence, Rhode Island say nine circus performers are in serious condition following an incident at the Dunkin' Donuts Center.
A Ringling Brothers spokesperson says this morning, eight female acrobats were doing a hair-hanging act.
Witnesses differ as to whether a scaffold collapsed or a cable snapped.
The women tumbled at least 25 feet to the ground and landed on a dancer.
Officials and investigators are checking into what happened.
Meanwhile, today's remaining shows and two others tomorrow are on hold.
