Star Rabbitohs fullback Greg Inglis will undergo scans after injuring his ankle in last night’s 34-18 win over the New Zealand Warriors in Perth.

Inglis limped off just before half-time after his leg twisted awkwardly in a tackle, with the 27-year-old Queenslander now in grave doubt for game two of the State of Origin series.

Benji Marshall produced his best performance in a St George Illawarra jersey last night as the Dragons thrashed an injury-plagued Cronulla 30-0 in Wollongong.

Penrith will lead at the halfway point in the season after a 36-14 win over Gold Coast.

The Newcastle Knights will be aiming to get their season back on track when they host Wests Tigers today, while the Storm take on the Roosters in Melbourne.
