The boxing competition at the 2008 Olympic Games got off to an enthralling start with Olympic and world champions in mixed form on the opening day of the 16-day tournament in the Worker's Indoor Arena in Beijing, China.

Two-time 75kg world champion Matvey Korobov (RUS) stormed to a 18-6 victory over Sweden's Naim Terbunja in the opening bout of the day before 75kg Olympic champion Bakhtiyar Artayev (KAZ) beat Said Rachidi (MAR) 8-2.

However, the big surprise result of the day saw 81kg world champion Abbos Atoev (UZB) go down to Asian Games champion Dzhakhon Kurbanov (TJK) 11-3 in one of the last bouts of the day.

Meanwhile, Samoa's Farani Tavui has been reported to be in a good and stable condition and will stay in the Chinese-Japanese Friendship hospital for observation after being knocked down in his 81kg bout against Croatia's 2005 world championship silver medallist Marijo Sivolija-Jelica.

Chairman of the AIBA Medical Commission Dr. Charles Butler, who was the officiating ringside doctor during the bout, commented that Tavui was sent to the hospital immediately as a "precautionary measure" and it is expected that he will stay in hospital for a few days under observation. 

The 2008 Olympic Games Boxing Competition continues on Sunday with two sessions, the first starting at 13:30 with 54kg and 57kg divisions in action.
