He was on Raw from Backlash to Summerslam, so he spent 4 months there.
He moved to SD the night after Summerslam, and stayed there until he left.
4 months on Raw = 16-18 weeks which probably means 10-15 matches, and I honestly wouldn't be surprised if he never wrestled on Raw again after Summerslam '02. Maybe at the 2003 Draft show? That would be the only chance.
