Roy, of 'Siegfried and Roy', attacked by tiger
(CNN) -- One of the tigers in Siegfried & Roy's Las Vegas show bit Roy Horn in the neck Friday night, seriously injuring him, according to a spokesman for MGM Mirage.
Emergency officials treated Horn at the Mirage Hotel-Casino around 8:20 p.m. (10:20 p.m. ET), for massive blood loss.
Clark County Fire spokesman Bob Leinbach said Horn was talking at the time emergency workers arrived, but had trouble breathing.
He was immediately transported to University Medical Center, where he underwent emergency surgery. The hospital would not release his condition.
A group of Australians witnessed the attack from the front row of the crowded theater, and said they thought it was just part of the show.
"A lady ran past me, freaking out and it was then I sort of, in the back of my mind, thought now this isn't part of the show," said David Strudwick. "And then you look at the staff and they had a bit of horror in their eyes and .. it was like, wait a second, it may not be a part of the show."
Horn, who was born in Nordenham, Germany, just turned 59 Thursday. Combining magic with tiger stunts, the duo has performed on the Las Vegas strip for nearly 30 years.
The tiger that attacked Horn is currently in quarantine and no one else was injured in the attack, according to Mirage spokesman Alan Feldman.
