Wales star Gareth Bale will have a scan on an ankle injury he sustained playing for Tottenham in the Europa League last night.
The 23-year-old has been in exhilarating form for club and country in recent months.
A collision with Basle midfielder David Degen was without malice, but looked to have produced a serious injury when Bale's ankle twisted awkwardly.
Spurs manager Andre Villas-Boas was optimistic though.
He said: "Gareth will definitely play again this season. It shouldn't be that bad."
