A day after Monday's wreck, Stewart was still scheduled for the World of Outlaws race Tuesday night at Ohsweken Speedway in Ontario. He's the defending race winner.
But the three-time NASCAR champion will sit out a pair of races this weekend as his team takes its cars to Indiana for repairs.
Stewart finished fourth Sunday at Indianapolis Motor Speedway and said he'd be in a race car every day this week. Although he declined to reveal his entire schedule, he said he was testing Wednesday, racing Thursday and would be at Pocono Raceway this weekend.
Spokesman Mike Arning says races Friday and Saturday night have been scrapped only for car repairs.
