Support just blokes in a team initially (8)
I believe the answer is:
abutment
'support' is the definition.
(abutment is a kind of support)
'just blokes in a team initially' is the wordplay.
'just' becomes 'but' (I've seen this in other clues**).
'blokes' becomes 'men' (I've seen this in other clues).
'in' indicates putting letters inside.
'initially' says to take the initial letters.
The first letter of 'team' is 't'.
'but'+'men'='butmen'
'a'+'t'='at'
'butmen' placed within 'at' is 'ABUTMENT'.
(Other definitions for abutment that I've seen before include "Structure supporting an arch" , "Arch-supporting structure" , "structural support" , "Meeting" .)
