Another sensational performance against Barcelona had the Celtic goalkeeper the toast of Scotland last week, but - still waiting for his England debut - he won't start on Friday for the biggest game England have played in years.
Forster is in the form of his life, while No 1 Joe Hart is suffering a horror season with one mistake after another.
But Roy Hodgson won't risk Forster or Norwich keeper John Ruddy.
Hodgson says "I'm going with what I know" . and what we ALL know is that Hart is a walking disaster at the moment.
Every member ofHodgson's 23-man England squad trained on Tuesday morning.
Hodgson's preparations for the game at Wembley hit a setback on Monday when Ashley Cole was ruled out because of a rib injury.
Hodgson called up Kieran Gibbs to replace the Chelsea man and the Arsenal defender joined in with the rest of the squad at Tuesday's training session in Burton.
Hodgson will be hoping to have all his players available for the clash at Wembley, and the home game against Poland four days later.
The England manager is without Theo Walcott, Alex Oxlade-Chamberlain and Glen Johnson because of long-term injuries, but he does have in-form duo Daniel Sturridge and Wayne Rooney available after they sat out the last double-header.
Rooney was the first of the outfield players to emerge on a sunny morning at St George's Park.
He was preceded by England's three goalkeepers Joe Hart, Fraser Forster and John Ruddy.
England go in to the final two games at the top of Group H, just one point ahead of Ukraine and Montenegro.
The only way they will definitely qualify for Brazil 2014 automatically is if they beat both Montenegro and Poland.
The only victories Hodgson has masterminded in qualifying so far have come against San Marino and Moldova.
