On March 26, 1951, Dambrot and his CCNY teammates Ed Roman, Ed Warner, Norm Mager, Al "Fats" Roth, Herb Cohen, and Floyd Layne were arrested on charges of shaving points in three games during the 1949–50 season. All pleaded guilty to misdemeanor charges of point shaving. All received suspended sentences, except for Warner, who received a six-month prison sentence.
According to a March 20, 1996, article in the New York Times by Ira Berkow, "the CCNY players who were convicted had accepted bribes from gamblers not to throw games, but to keep them under the point spreads. The players received just a few thousand dollars for their efforts, which took place during the season, but not during tournament games."
