Unfancied team no longer in the dressing room? (7)

I believe the answer is:

outside

'unfancied' is the definition.
(the outsiders in a match, not fancied to win)

I don't understand how the rest of the clue works.

(Other definitions for outside that I've seen before include "having emerged from the tunnel?" , "In the fresh air?" , "Al fresco" , "External surface" , "Without" .)

I've seen this clue in The Times.
