📜 Historic: The “double tap” controversy; Bustamante later stripped for signing with PRIDE; Lawler debut
The Double Tap Controversy
In the first round, Bustamante secured a deep armbar on Lindland. Lindland’s arm was fully extended and he appeared to tap. John McCarthy stopped the fight. Lindland immediately protested, claiming the tap was reflexive and not intentional. McCarthy, in an unusual decision, restarted the bout. The sequence was captured on video; the tap appeared to be a legitimate submission signal.
The fight continued. Bustamante worked through two more rounds and finished Lindland with a guillotine choke in the third round at 1:33. The result was not affected by the controversy — Bustamante won regardless. But the armbar incident remains one of the most discussed referee decisions in early UFC history, a case study in what constitutes a tap and how referees should respond to contested signals.
Robbie Lawler’s UFC Debut
Robbie Lawler was 20 years old when he fought Aaron Riley at UFC 37 in his first UFC appearance. He won by unanimous decision over three rounds.

The UFC Middleweight Championship went vacant, and would not be contested again until UFC 51 in February 2005 — when Evan Tanner defeated David Terrell for the belt.
