The motocross star, 27, broke bones in his right foot and ankle after crashing during the Moto X Best Trick event at the X Games in Los Angeles. Pastrana was attempting a corked 720 he's dubbed "the toilet paper roll" when he fell.
"Travis can be in a lot of pain and shake it off, like, 'Let's do it again,' " an X Games producer who witnessed the crash tells PEOPLE.
"But when the crew came over he was limping and on one foot. You knew it was bad, but you didn't know what exactly – just, 'Oh no, that's not good.' "
Pastrana – who got engaged last month – was released from the hospital Thursday evening, with his injuries requiring surgery at a later date.
"I am sorry this happened and will be back in action as soon as I can," he tells ESPN.
"He's capable of such amazing things – you're excited to see what he's going to do," says the producer. "It was unfortunate for everybody to see it happen, especially on the first day [of the X Games]."
