In early 2007 it was announced that Mark Gasnier, Ben Hornby and Jason Ryles would captain St George Illawarra. Controversially, given his reputation as centre, Gasnier was moved to for the Dragons following Trent Barrett's move to the Wigan Warriors. However, Gasnier tore his pectoral muscle tackling Nigel Vagana in the Charity Shield pre-season trial and was unable to play again until July. On 21 July, Gasnier made his long-awaited return to the Dragons, in the five-eighth position, with his team winning 38–20 against the Penrith Panthers. Despite Gasnier's shortened season, he was selected for the Australian Kangaroos in October to play the New Zealand Kiwis in Wellington. Gasnier spent 24 minutes on the field before being knocked out by a Steve Matai high tackle. Suffering from concussion, Gasnier was unable to participate further in the game.
