Concerns over Samu Kerevi as Wallabies prepare for World Cup opener

Wallabies inside centre Samu Kerevi is in doubt for Australia's first game of the Rugby World Cup after only completing parts of training in France on Tuesday, reports The Sydney Morning Herald.

Ahead of the Wallabies' biggest session of the week, in the lead-up to their first game against Georgia on Sunday morning (AEST), Kerevi was not involved in the warm-up.

The Fiji-born star was the only player from the 33-man Wallabies squad who was not on the field in the 15-minute window for reporters to take photos and video.

He was later seen in a dugout without his boots on as his teammates got the session underway.

Kerevi has been dealing with a hand injury since Australia's 23-20 Bledisloe Cup loss in Dunedin and did not face France in a warm-up match on August 27, when the Wallabies were thrashed 41-17 in Paris.

The team has given little away regarding Kerevi's availability for the Wallabies' tournament-opening clash with Georgia, but the 29-year-old's limited involvement points to him not being selected.
