'American Idol' Rehearsal Canceled After Injury, Raining Glass

Stage manager was rushed to the hospital following a mishap on the staircase.

As if performance night for the "American Idol" top four weren't dramatic enough, just hours before Adam Lambert, Kris Allen, Danny Gokey and Allison Iraheta took the stage in Los Angeles, TMZ reported that stage manager Debbie Williams was injured in a mishap on the show's giant staircase during dress rehearsal.

The staircase, which is supposed to retract as host Ryan Seacrest walks down it, reportedly folded too soon on Tuesday afternoon (May 5), and Williams, who was following Seacrest, tried to hold on but instead tumbled down the stairs. She suffered what was described as a "nasty gash" on her leg and was taken to a local hospital.

"We have had an unconventional day," Seacrest said at the top of Tuesday night's show. "Had a couple of things happen here on this set. Unfortunately we had an accident earlier here on our stage, but it didn't end there."

In addition to the mishap that befell Williams, Seacrest pointed to the two giant globe-like "Idol" logos that flank the stage, one of which was hanging nearly upside down. He said it "collapsed" just a few moments before that afternoon's dress rehearsal, sending shards of glass all over the stage, with TMZ reporting that the studio was cleared as a mild panic ensued. "So the contestants have not had a proper run-through for the show," he said. "But as they say in Hollywood, the show must go on."
