The Nitro Circus Live show is kicking some serious goals and breaking a whole swathe of records as the crazy bunch of hillbillies and action-sports doyens invade stadiums and show grounds around Australia and New Zealand.

The promoters have posted record-breaking sales for any live touring act across the two countries, and to a man (or child) everyone has left the stands with beaming grins, incredulous shakes of the head and promises they'll come back again next year.

But sometimes things don't always go to plan. Last weekend's show in Australia's capital, Canberra, saw some of the biggest names in FMX find themselves in the back of an ambulance and heading to the local hospital; the show's front man Travis Pastrana, Aussie double flipper Cam Sinclair, and one of the country's most clinical riders, Steve Mini, were all casualties.

From what we can understand Travis experienced severe pain in his leg before the show, and after the tour's physiotherapist tried in vain to address his rapidly-swelling leg, Travis ordered an ambulance take him to hospital. Initial reports were pretty sketchy, but the general census from inside the Nitro camp were suggesting it was a suspected blood clot, or blood rushing to a muscle around his knee area. However it has now been confirmed that was a hugely swollen and painful hematoma on his thigh.

"It was pretty full-on. I've known Travis for more than a year now, but I've never seen him in that much pain," says wheelchair Front-flipper Aaron "Wheelz" Fotheringham. "He was taken to hospital and missed the show. It was the first time we've held a show without Travis being there, and it was weird."

The next casualty was Mini, who went down hard just 15 minutes into the event when he missed the grab-hole on his incredible four-trick combo (holy grab to one-hand indy to rock solid to no-handed lander) and plummeted back to earth.

The crash resulted in a dislocated shoulder, tendons torn from the top of his arm (taking away chunks of bone with it), a broken big toe, bruised heel, dislocated thumb and seriously bruised buttocks.

"Somehow I managed to get my feet down and fell onto my side, and my arm was folded so far it felt like my shoulder rolled around into my back," Mini said. "All the boys said it was a huge crash and it was the worst pain I've been in.

"Last night's show had a bad feel right from the start," he continued. "Conditions were good, but after we announced at the start of the show that Travis wasn't going to be present the crowd was pretty hard to get going, and I think it must've screwed with our minds a little."

Mini-Dawg will miss the next two shows while he rests up at his parents' home in Mudgee, with Robbie Adelberg receiving the call-up to fill Mini's seat in the show.

But that wasn't the end of the carnage. While Mini was still in hospital he received word that Cam Sinclair had under-rotated his double backflip and been taken to another hospital with serious concussion and for precautionary scans of his head, shoulder and chest.

"I don't remember much from the three days leading up to the show," Sincs told us. "I vaguely remember the double flip. I thought I was under-rotating and I tried to turn my body to the side so I didn't get driven into the down-ramp like I did in Madrid. I'm think that saved me from getting more f---ed up, even though I'm sore as hell at the moment. Laying in bed last night has stiffened me up bad."

Sincs still doesn't know the extent of his injuries, but he visited a shoulder specialist early in the week, where he got a referral for an MRI scan.

"I don't think anything's broken," the 26-year-old said while recovering at his Melbourne home. "I've broken my shoulder blade twice before and that was a lot worse than this -- this feels more like some major bruising, but I guess we'll find out on Monday."

Sincs is hoping to be back in time for the Townsville stop of the tour, but even then he doesn't know when he'll be busting double rotations.

"It's a pain in the a-- of a trick. I thought I had my head around it after Madrid, but I crashed one in New Zealand, and then screwed this last one up as well. I'm starting to wonder if it's one of those tricks that you can never quite master completely. Maybe it's best left for the Best Trick contests."

We wish all the boys a speedy recovery and safe travels for all the athletes as the complete the remainder of the mind-blowing Nitro Circus Live Australia Regional Tour.
