On May 16, 1975 he was given an opportunity to face heavyweight champion Muhammad Ali, during Ali's second title defense in his second reign as champion. Lyle had Bobby Lewis and Chico Ferrara in his corner. Lyle was the more aggressive fighter in the early rounds, with Ali conserving his energy and covering up in the center of the ring allowing Lyle to score. Lyle also showed restraint and did not respond to Ali's attempts at the rope-a-dope ploy. Though in danger of falling too far behind on points, Ali appeared to be in control of the pace of the fight, and picked his moments to score. The fight was close going into the 11th round, with Lyle winning on all three of the judges' score cards. Ali then hit Lyle with a strong right hand and followed with several flurrying punches, scoring. The referee stopped the fight, seeing that Lyle was unable to defend himself and Ali was punching him in the head at will. Lyle's corner was not happy with the referee's decision.http://video.google.com/videoplaydocid=3996128832928221414#
