The New Jersey-bred colt, who is a perfect 3-for-3 in his career with three stakes wins, including the California Derby, was set to be one of the favorites in next week's race.
"The horse came back from galloping this morning and was injured, " said Hollendorfer by phone from Santa Anita. "There's no way to know why, or, actually, what happened, but the horse can't run. He's going to have to have some time off and that's all I can tell you."
Hollendorfer had planned to run both Exit Stage Left and Puppy Manners in the race but now will bring up Tamarando for the race. Tamarando, winner of the Grade 1 Del Mar Futurity, will be ridden by Russell Baze.
In other El Camino notes, according to agent Craig O'Brien, Gary Stevens is planning on riding the Tom Proctor trained Enterprising in the race.
