The Manchester United midfielder had to withdraw from the squad due to an injury, with the Liverpool man now hoping to add to his sole cap against Poland on Tuesday
The 18-year-old has been rewarded for a superb start to the Premier League season by national coach Roy Hodgson, who has been forced to draft in midfield cover following an injury to Manchester United's Tom Cleverley.
"Raheem Sterling will join up with Roy Hodgson's senior England squad ahead of Tuesday's final World Cup qualifier against Poland," a statement from the FA confirmed.
Sterling, who played 65 minutes in England Under-21s' 4-0 win over San Marino on Thursday, has one senior cap to his name having made his debut in the 4-2 defeat against Sweden last November.
His only other appearance in an England squad was for a qualifier against Ukraine in 2012.
England head into next week's Wembley clash knowing that victory will qualify them automatically from Group H for next year's finals in Brazil following their 4-1 triumph over Montenegro on Friday.
Hodgson will also be without the suspended Kyle Walker for Tuesday's game.
