KEY POINTS:
Legendary American boxer Muhammad Ali returned to Madison Square Garden to cheers of "Ali, Ali, Ali" and watched his daughter Laila, 28, defend her world super middleweight title on Saturday.
The cheers continued for Laila, who used a left-right combination to bust the nose of challenger Shelley Burton in the fourth round, retain her WBC women's crown and improve her record to 23-0.
Minutes before her fight, Ali and his entourage entered the arena, the former world champion looking frail and shaking violently from his Parkinson's disease.
Said Laila: "It's always great to have him watching me fight."
