Andy Murray begins Olympic title defence against Viktor Troicki in Rio

Team GB flag bearer Andy Murray will face Viktor Troicki in the first round of the men's Olympic singles event. The world number two beat Stan Wawrinka, Jarkko Nieminen, Marcos Baghdatis, Nicolas Almagro, Novak Djokovic and Roger Federer to triumph at London 2012 and begins his gold medal defence at the Rio Tennis Centre in Barra da Tijuca this weekend.

Currently ranked by the ATP at 35, Troicki, like Murray, sat out Great Britain's Davis Cup quarter-final victory over Serbia last month. The right-hander has never progressed past the fourth round of a grand slam and previously served a reduced one-year suspension for an anti-doping rule violation relating to his failure to provide a blood sample during the 2013 Monte Carlo Masters.

He also made headlines at this summer's Wimbledon Championships for an angry tirade aimed at umpire Damiano Torella during a second-round loss to Albert Ramos-Vinolas, and his tour record against Murray stands at seven defeats in as many matches.

They last met in the semi-finals of the 2015 Aegon Championships, where the home favourite won in straight sets 6-3, 7-6 en route to claiming the fourth of his record five Queen's Club titles. The duo also crossed paths at Wimbledon in 2009 and at Roland Garros two years later.

Murray's projected route to the final does not look overly complicated at first glance and is likely to take in matches against the likes of Juan Monaco, Benoit Paire, David Ferrer and Kei Nishikori before another potential showdown with Djokovic in the final. The 29-year-old will also partner older brother Jamie in the doubles and they begin that campaign against Brazilian pair Thomaz Bellucci and Andre Sa.

Elsewhere for Great Britain, men's number two Kyle Edmund takes on Australian Jordan Thompson and Stephanie Vogt of Lichtenstein is first up for 10th seed Johanna Konta. Heather Watson meets China's Zhang Shuai and doubles partners Dominic Inglot and Colin Fleming entertain Santiago Gonzalez and Miguel Angel Reyes-Varela of Mexico. Konta and Watson team up to battle Serbians Jelena Jankovic and Aleksandra Krunic.
