The veteran international suffered a knock in Thursday's England training session, and thus needs to be out of action for a while.
Media reports mentioned that his layoff could be around two months; even so, Capello believes that Lampard might make his return in a fortnight.
"I think he will be out for two or three weeks. It is a little problem with his muscle," he said.
Capello also refuted reports claiming that Lampard was injured as a result of cramped conditions on his team's flight to Qatar, where England are preparing for their friendly to Brazil.
"I don't understand the problem," the former Real Madrid coach added.
"It was the same plane we used to go to Trinidad last year and also Kazakhstan this year. We didn't have any injuries then and we won both matches.
"Frank came to me and said he had suffered this problem before, which was why he had stopped running.
"It was best to let him go home but, I think, in two or three weeks, he will be okay to play again."
