"Judgment Week" is coming to NBC's America's Got Talent on Tuesday, and not all the acts that made it through auditions will make it into the next round.

America's Got Talent Renewed For 10th Season

On Thursday, NBC released an extended preview (featured below) of the elimination round, which includes plenty of blood, sweat and tears to go around.

The preview started off on a high note, with each of the four judges traveling to different parts of the country to inform their favorite acts that they have been given a free pass into the live shows at Radio City Music Hall. These numbers will be excluded from the next round of eliminations, allowing them some relief for the time being.

Others performers, however, won't be so fortunate. They will be competing to stay in the competition, each only given one opportunity to make an impression. With only 47 slots available, half of the talent acts will be cut during "judgment week."

"The battle will be intense...Some will rise to the challenge," teased host Nick Cannon. "Others will find the pressure overwhelming." Certainly "intense" is no understatement. The preview continued tease a few acts riddled with mistakes, fault, and in one case, an injury resulting in an ambulance call.

The performers, however, aren't the only ones facing challenges ahead. The judges will find themselves divided over acts, struggling to push their favorites through into the lives shows.

"The level of talent is beyond anything we have ever seen," declared judge Howard Stern.
