Former two division world champion Sergio "Maravilla" Martínez has officially confirmed that his return to the sport of boxing will be against Spanish contender José Miguel Fandino (15-6, 8 KOs), in a fight to take place in the middleweight division.

The contest is scheduled to take place on Friday August 21, in the municipality of Torrelavega.

Martínez confirmed the date change during an interview offered this afternoon to Chronicle TV. The card was initially scheduled for Saturday, August 22, and seems to have been pushed back by 24 hours, to Friday the 21st.

The fight will be scheduled to take place over ten rounds, in Torrelavega, which is a city located in northern Spain, near Bilbao and about 400 kilometers from Madrid.

The boxing festival of that evening will showcase a championship contest in the main event, as Spain's Sergio García will defend the title of European super welterweight championship.

The 45-year-old Argentine boxer, who was world champion at super welterweight and at middleweight, will fight again after six years and two months against an opponent 10 years younger, nicknamed "the traumatologist".

Martinez was last seen in the ring back in 2014, when he was knocked out by Miguel Cotto.

Fandino last appeared in Oviedo in November, when he beat his compatriot Sergio Fernández with a resounding knockout in the second round to win the vacant Iberoamerican super welterweight title from the International Boxing Organization (IBO).
