St George Illawarra fullback Josh Dugan has suffered a hamstring strain and will miss the Dragons' next two NRL Telstra Premiership fixtures.

Dugan suffered the injury midway through the second half of the Dragons' 28-6 win over the Wests Tigers at ANZ Stadium, Olympic Park on Sunday afternoon.

The New South Wales and Australian international will aim to return on Anzac Day in the traditional clash against the Sydney Roosters at Allianz Stadium.
