Jimmy Vasser's return to competition at Toronto was short-lived after a hard landing in one of Robby Gordon's trucks sent the former champion to the hospital for X-rays. Vasser was scheduled to run both Saturday and Sunday in the Gordon-owned Speed Energy Stadium SUPER Trucks series, but only made it through two laps in Saturday morning's practice because of a rough landing. Vasser said he did exactly the opposite of the instructions Gordon gave him before practice for the series in which trucks slide through the corners and jump ramps that make the trucks sail 50 feet through the air. "Robby told me to lift off a bit before the ramp, and then power up the ramp," Vasser said. "Apparently I didn't lift enough, and I powered more than I should have. I looked out the window and I was over the fence line and it was pretty cool -- until I landed and the whole truck hit the ground, and my back went crack, crack, crack."
