London, England (Sports Network) - Cuban Mijain Lopez Nunez successfully defended his Olympic gold medal on Monday in the men's 120 kilogram greco- roman division.
Nunez is a four-time world champion and took gold in this event at the 2008 Beijing Olympics. He bested Turkey's Riza Kayaalp in the semifinals, avenging a loss at the most recent world championships.
The 29-year-old then defeated Estonia's Heiki Nabi 3-0 in the final and didn't rule out participating at the next Summer Olympics.
"I am considering it. I would like to. But I am 30 and it becomes more complicated to stay at the top. These were my third Olympic Games and life goes on. So let's see," Lopez Nunez said.
While Nabi took silver, Kayaalp rebounded to earn a bronze medal, as did Swede Johan Euren.
Youngster Alan Khugaev emerged from the 84kg competition with gold after scoring a win over Egypt's Karam Mohamed Gaber Ebrahim.
The 21-year-old Khugaev finished fifth in last year's world championship and had to beat the current world champ, Belarus' Alim Selimau, in the 1/8 final to advance.
Ebrahim's silver was his second Olympic medal as he won gold in the 96kg division at the 2004 Athens Games.
Poland's Damian Janikowski claimed one of the bronze medals, giving his country its first Olympic medal in greco-roman since 1996. The other bronze went to Kazakhstan's Danyal Gajiyev, who had wrestled for Russia until January of last year.
Current world champion Omid Haji Noroozi of Iran claimed gold in the 60- kilogram bracket, beating Georgia's Ravaz Lashkhi in the final. Noroozi went 15-2 in points over his five matches and didn't yield a point in the semis or finals.
Japan's Ryutaro Matsumoto and Zaur Kuramagomedov of Russia won bronze medals, with the latter beating former world champion Hasan Aliyev of Azerbaijan.
