Another three bouts were eventually ruled no-contests (NC). The first, in Los Angeles on March 12, 1977, was a nine-round NC (WKA) against Thai boxer Narongnoi Kiatbandit as part of the inaugural WKA world title event. Urquidez scored flash-knockdowns against Narongnoi in rounds three and six as well as five legal throws over three other rounds. Narongnoi was warned for illegal knee kicks and groin attacks on four occasions before being assessed with a point deduction in round nine. However, the point deduction came shortly after Narongnoi had scored his sole flash-knockdown which, in turn, provoked a riot among Muay Thai fans in the audience. The audience invaded the ring moments before the final bell. Scores were never collected for round nine. The California State Athletic Commission declared the no-contest.
