Semesa Rokoduguni is highly likely to miss Bath's Premiership clash with Harlequins on Sunday.
The powerful wing is available to play for the British Army as they meet the Fiji Army in the final of the Defence World Cup in Twickenham Friday.
The British Army beat New Zealand 40‑15 in the semifinals.
Rokoduguni played earlier in the competition against Australia's armed services and scored a hat‑trick.
The Fiji Army on the other hand beat the French Armed Forces 37‑12 in their semifinal.
The trophy which the teams are contesting commemorates the selfless sacrifice of Arthur Harrison, the only England rugby international to win the Victoria Cross.
Other Fiji born players who will feature for the British Army rugby team are Ifereimi Boladau, Joe Nayacavou, Makulusio Koroiyadi and Glasgow Warriors wing Junior Jonasa Bulumakau.
The final between the British Army and the Fiji Army kicks off at 7am Friday.
