Ospreys boss Steve Tandy wants his Wales players to re-adapt quickly to regional rugby ahead of Friday's Heineken Cup game in Castres.
The Welsh region missed several internationals and suffered a home defeat to Glasgow last weekend. But they will be bolstered by the return of several Test players from Wales' recent end-of-year campaign.
The returning players will, however, have little time to acclimatise to life back at the Liberty Stadium as they immediately face a crucial European match in France.
After losing their opening Heineken Cup encounters, to Leinster and Northampton, the Ospreys need something from this match to revive hopes of reaching the competitions' knockout stage.
"We'll probably have two sessions and then we'll travel to Castres so it is limited preparation, but it's something we've got to deal with," Tandy told the South Wales Evening Post.
"We've got to prepare as best we can in two sessions, it's as simple as that. But we can't be looking for excuses. We've got to find a way to produce a performance.
"Losing the first two games doesn't help. The home game against Leinster was the biggest disappointment when we felt we'd done enough to win.
"But if we can get a win you never know how things will go because I think other teams will knock each other over."
