Andrew Trimble is set to be available for the France game

Ireland wing Andrew Trimble may be out of Saturday's World Cup game against Georgia but he is expected to be fit for the key clash with hosts France.

The Ulsterman, who fractured a finger in the 32-17 win over Namibia at the weekend, should be available to face the French on 21 September.

"Andrew should be fine for France," said assistant coach Niall O'Donovan.

Leinster's Shane Horgan replaces Trimble in the only change to the line-up for the Georgia game.

"Unless we pick up any fresh injuries against Georgia on Saturday, we should have a fully fit squad for France," added O'Donovan.

Georgia lost 33-3 to Argentina in their opener on Tuesday.

Horgan suffered a knee ligament strain while warming up before August's friendly with Scotland and has completed his rehabilitation on schedule.

Captain Brian O'Driscoll, Marcus Horan and Ronan O'Gara have all been passed fit following minor injuries picked up in the Namibia match.

O'Driscoll hyper-extended an elbow in the opener, fly-half O'Gara bruised a foot and prop Horan suffered a back injury.

Ireland lie second in Pool D, four points behind an Argentinian side which has played an extra game.

Ireland: G Dempsey, S Horgan, B O'Driscoll (capt), G D'Arcy, D Hickie, R O'Gara, P Stringer, M Horan, R Best, J Hayes, D O'Callaghan, P O'Connell, S Easterby, D Leamy, D Wallace.
