Air Gravity attended the Birmingham auditions recently to showcase their act, which sees them leap between trampolines.
The gymnastic group from Northamptonshire previously came second on ITV's Let's Get Gold in 2012.
However, a male member of the troupe crashed during a flip, and suffered a dislocated shoulder, according to The Sun.
He was taken to hospital by show medics, and is said to have made a recovery.

"But, towards the end of the act, one guy bounced from one trampoline to another and grimaced with pain when he landed."
Amanda Holden and Alesha Dixon staged a walk-out on the final day of Britain's Got Talent auditions earlier this week.
Britain's Got Talent returns to ITV in the spring.
