Wales scrum-half Mike Phillips could be available to play in the Dragons' final end-of-year Test against Australia on December 1.
Phillips was expected to return to his club, Bayonne, after Saturday's clash with the All Blacks as the Wallabies match falls outside the IRB's international fixture window.
But last-minute negotiations are currently underway between Bayonne officials and their Welsh Rugby Union counterparts in an attempt to keep Phillips with the Welsh squad for another week.
The move comes after recent meetings between Wales coach Warren Gatland, his assistant Rob Howley and several Top 14 clubs as Wales' management look to build relationships with French clubs amid the player drain across the channel.
Wales have already reached agreement with Perpignan to allow Luke Charteris to be available for the Wallabies Test.
This resulted in the second-rower instead missing the Dragons' recent Test against Argentina in order for him to play against Biarritz in the Top 14.
Bayonne take on Montpellier on December 1 - the day of the Australia Test.
"I might be able to play against Australia," Phillips told Walesonline
"I'm not quite sure at the moment as it is up in the air.
"Hopefully, I will be able to play as it is always special to put on that red jersey."
Wales are also hopeful Toulon prop Gethin Jenkins, who missed out on selection against New Zealand, will also be released by Toulon.
Jenkins is second-choice behind Andrew Sheridan at the Top 14 leaders and his availability is likely to be dependent on the England front-rower's fitness.
Perpignan utility back James Hook and Bath prop Paul James, who starts at loosehead this against the All Blacks, will both leave the squad after this weekend's match.
