Summer sports federation say progress made in Rio but timelines still tight for 2016 Olympics

Eight months after warning that the 2016 Olympics were at risk because of delays, sports federations say Brazil has made "considerable progress" but must accelerate preparations for the Rio de Janeiro Games.

The Association of Summer Olympic International Federations says the crisis has eased since the sports publicly raised concerns over Rio's delays at a meeting in April in Belek, Turkey.

But ASOIF said in a statement Monday that "timelines remain tight for the construction of the venues."

The association added that "progress with operational planning and implementation must increasingly be the priority as we are now well inside the 'two years to go' marker."

ASOIF said it has been asked by the IOC to play a greater role in monitoring Rio's progress.

The statement came following a meeting of the ASOIF Council in Lausanne.
