Scotland will be without key midfielder Scott Brown due to a hip injury for their must-win World Cup qualifier against Belgium in Brussels on Tuesday.
The Celtic man was forced off at half-time of the 2-1 defeat to Wales on Friday evening and has been replaced in Craig Levein's squad by Cardiff City's Don Cowie.
Levin also has doubts over Brown's Celtic team-mate James Forrest (groin) and Hearts defender Andy Webster (back), while Everton striker Steven Naismith sits out as he completes a two-match suspension.
Having taken just two points from their opening three qualifiers, Scotland need to go in search of three points against an ever-improving Belgian side who have seven points from three games.
Belgium are 1.33 to take all three points on Tuesday, with the draw 4.50, while Scotland are 11.00 to pick up a shock victory.
Midfielder James Morrison has urged his side to go all-out for a win, feeling that any other result would all but end their hopes of qualification.
He said: "There is probably a little bit of hope if we win in Belgium. We get that belief again and that's all we can do.
"We've got to regroup quickly or else the group is going to pass us by. Basically, we've got to win in Belgium."
