SYDNEY (AP) -- Shane Mosley was stopped in the sixth round by former rugby league player Anthony Mundine in a WBA international super welterweight title fight on Wednesday. It was first time the 42-year-old American failed to go the distance.
Mosley quit before the seventh round because of back spasms. His record dropped to 47-9-1 and he said he'll decide on retirement after he returns to the United States.
''What's done is done,'' he said when asked if he would fight again.
The 38-year-old Mundine improved to 45-5 with 26 knockouts at Homebush in western Sydney. Mundine was leading 58-56 on two cards and 60-55 on the third.
''I was in killer mode, but my heart goes out to Shane. I know he's a winner,'' Mundine said. ''He's not one to pull out for nothing. He's one of the greatest fighters to have ever lived.''
The fight was delayed for five weeks because of financial issues.
American referee Raul Caiz Sr., who has worked two of Mundine's past bouts and one of Mosley's, stopped the fight on the recommendation of ringside doctor Lou Lewis.
In another bout, heavyweight Blake Ferguson, a former rugby player, lost a four-round unanimous decision to Luke Turner.
