The NRL has kiboshed Canberra's hopes of hosting a potential grand final qualifier, with the game set to be moved to Sydney if the Raiders continue their impressive form and make it that deep into the season.

The Raiders, of course, have to maintain their upward trajectory if they want to stamp themselves as a genuine threat, but they sent a warning to the competition by beating the Cronulla Sharks last weekend.

They play the Melbourne Storm in Canberra on Monday night and another win will paint Canberra green with just a handful of games left before the finals. Is the NRL right in moving the preliminary final (the game before the grand final) to Sydney if Canberra has hosting rights?

While the Raiders ride high, the Brumbies have heavy hearts after Christian Lealiifano was diagnosed with leukaemia last week.

The Olympic Games continues to bubble away in Rio with some success in the pool, but Canberra's golden moment came when Sharni Williams led the Australian sevens team to a gold medal.

Williams was injured for five months before the Games and traded her life as a mechanic to chase a dream that started when she was just eight years old.

One man who's not at the Olympics is Nick Kyrgios, but the tennis star won his second APT title in Atlanta and now has a career-high ranking of No. 16.

Does that win and his new ranking vindicate his decision to withdraw from Rio calculations?
