Motocross legend Travis Pastrana pulled out of the Moto X Best Trick competition Wednesday, one day before competition at X Games 16 begins.

The star of MTV's Nitro Circus was planning to attempt the same move he failed to land at last year's games: the 720 toilet paper roll. But a poor performance during his practice session this morning convinced him it was best for him to pull out.

After nailing the move 3 of 5 times a few days ago, he went zero for five in his latest attempts. "I'm just not comfortable with those odds," he said. "Especially when I'm still recovering from last year's hard landing...I still can't sit right since the crash."

Pastrana will still be plenty busy this week, with Speed and Style and two rally car competitions on his plate.

He's hardly the only X Games star to make a last minute exit. BMX star Dave Mirra has pulled out of the Park competition due to soreness in his back. Mirra gave it a shot in practice on Tuesday, but wasn't feeling it. Mirra will also be competing in both rally car disciplines at this years X Games.
