Dismissed just for being unqualified (8)
I believe the answer is:
outright
'being unqualified' is the definition.
(similar in meaning)
'dismissed just' is the wordplay.
'dismissed' becomes 'out' (dismissed in cricket).
'just' becomes 'right' (similar in meaning).
'out'+'right'='OUTRIGHT'
'for' is the link.
(Other definitions for outright that I've seen before include "Unreservedly" , "Total" , "Not qualified" , "Without qualification" , "Completely and entirely, not gradually" .)
