Ospreys medical performance manager Chris Towers has revealed that the Welsh region's winger Jeff Hassler will be unable to play for the next four weeks, after he sustained a knee injury while playing for Canada at the World Cup.
It is believed Hassler continued to play with his injury throughout the remainder of the campaign, before his team was eliminated form the tournament.
"Jeff returned from the Rugby World Cup with a knee problem which he had played on with throughout the competition," said Towers.
"We've assessed the injury, and sought a second opinion, and due to the nature of the issue we've been left with no option other than to offload him to allow it to settle down. I'd anticipate that it will be a period of at least four weeks before he will be fully fit to return to playing," added Towers.
Naturally, the injury has re-ignited the debate about the effects of international rugby on domestic teams. One person who has expressed some concern is Ospreys Rugby general manager Andrew Millward.
"Although World Rugby commented earlier this week that the number of injuries at this tournament do not appear to be higher than normal, that doesn't match with what we are seeing for ourselves and we would welcome the opportunity to sit down with them and look at their findings," he said.
"The reality is that clubs like ourselves who take great pride in developing players for international rugby, supplying almost one third of the Wales squad plus players to Canada and Fiji, are being hit hard as a consequence."
