The injury disclosed Friday is Bale's 19th since joining Real Madrid four years ago from Tottenham Hotspur and he could be sidelined for anywhere from 10 to 30 days.
There has been no timeline mentioned yet on his return, however, fans can be assured that they will be seeing a lot more of Isco rather than Bale.
He is likely to be available for the Madrid derby against Atletico after the global break.
A statement published on realmadrid.com said the 28-year-old had been diagnosed with a fibrillar rupture to the adductor of his left leg.
He had returned to training last week and was named in Wales' squad for friendlies against France and Panama. "His recovery will continue to be assessed".
There is no estimate for the length of time the Real star will be missing but it is just the latest in a series of injury blows that have blighted Bale in 2017.
Indeed, including Bale's bumper salary, AS believe his 159 games for the club have cost Madrid 1.06 million euros a match.
The Wales worldwide has sustained another injury setback and is expected to be out for close to a month.
