Kimmorley warns Sharks against

Cronulla captain Brett Kimmorley has warned the Sharks their stirring win over Newcastle will mean nothing if they lose tonight's crucial NRL clash with Canberra at Toyota Park.

Kimmorley says Cronulla's 30-24 comeback win over the Knights has given the Sharks a massive boost. But they must continue their three-game winning streak to stay in touch the competition leaders.

A slip-up against the front-running Raiders tonight would leave the Sharks in 12th spot and four points adrift of the top eight a week out from the halfway point.
