Novak Djokovic exits Rio 2016 in tears after shock defeat
Novak Djokovic has left the Rio 2016 court in tears after a surprise first round defeat to an opponent who got stuck in a lift on the morning of the match.
Former US Open champion Juan Martin Del Potro, who is now ranked 141st in the world after a series of injury problems, won 7-6 (7-4) 7-6 (7-2) to end the top men's seed's hopes of an Olympic tennis medal.
Del Potro had earlier been trapped in an Olympic Village lift for 40 minutes before being rescued by members of Argentina's handball team.
