Bale was a notable absentee as Tottenham rounded off their pre-season campaign with a 1-1 draw against Espanyol at White Hart Lane, where summer signing Roberto Soldado marked his home debut with a goal from the penalty spot in the first half.
Villas-Boas said: "The only thing I can say about the stories is I am not going to comment because everybody has speculated a lot. There are some different stories, some which are not true, with people inventing without knowledge of what is going on.
"The only thing I can tell you is the player is under the treatment of the medical department for this pain in the foot which is disturbing him.
"He has been called up for his national team [for a friendly match against the Republic of Ireland], our medical department is going to be in contact with the Wales medical department to make sure they have everything available in terms of giving information on how the player has been doing in these last weeks.
"Regarding the speculation, I don't want to extend myself further than I have told you."
