BROOKLYN, Mich. (AP) — This was exactly the kind of scenario Kyle Busch needs to avoid.Busch slid onto the grass after coming through a turn during NASCAR Sprint Cup practice Saturday, damaging his No. 18 Toyota. He returned to the track in a backup car, but he now faces the prospect of having to start from the back Sunday in the 400-mile, 200-lap race at Michigan International Speedway."I was just running along, everything was fine and I was actually feeling pretty good about it," Busch said.
