Real Madrid manager Carlo Ancelotti had revealed on Wednesday that the Wales player had picked up a muscle strain in his left thigh and was expected to be out of action for 15 days.
"We are not worried but he was not able to play today (in a 4-0 win over Copenhagen) because he has a little problem," the Italian said. "He had a scan, it didn't show anything special but he has just to recover his condition.
"Now we have the time because we have 15 days. I think that in 15 days he will be ready to play with us."
That meant Bale would miss Saturday's La Liga game at Levante and Madrid expected him to also be excluded from the squad for the World Cup qualifiers at home to Macedonia on October 11 and away to Belgium four days later to ensure he had fully recuperated.
"It's not a problem because now we have time to get him into good condition to avoid further injury," Ancelotti added.
However, despite being named in the squad, Bale will not play a part in either match as Wales boss Chris Coleman confirmed the 24-year-old would not feature.
Coleman said: "We have spoken to the doctor and we will be without him, but we said all along it is very tough for him to have had no pre-season and be thrown in at the deep end."
He added: "I would never criticise another manager - Carlo Ancelotti is a brilliant manager - but La Liga football is a different tempo to the Premier League. The Premier League is the fastest so maybe Carlo is thinking Gareth can handle it, he's a super athlete.
"But in our last camp he was nowhere near fit. He had a reaction on the morning of the Macedonia game, that is why we only used him for 35 minutes against Serbia last month.
"You have to put things in perspective. What has happened to him with the move, he must feel under pressure.
"He is probably trying too hard to do things that come naturally to him. Physically he is not there, he is not ready and he might not be for some time.
"If you don't do a pre-season, no matter how good you are, you always play catch up for the season. This season might be a tough one for him, as good as he is.
"On top of that he has had the weight and stress of 'Will the move happen, won't it?' and then it happens.
"I think he has gone into it when he is not at his fittest physically or mentally. It has had an affect.
"I hope I am wrong but I don't think it will be the last injury he gets this season because of the stress of everything."
