Put at risk in final, and see red (8)
I believe the answer is:
endanger
'put at risk' is the definition.
(I've seen this before)
'final and see red' is the wordplay.
'final' becomes 'end' ('end' can be a synonym of 'final').
'and' is a charade indicator (letters next to each other).
'see red' becomes 'anger' ('anger' can be a synonym of 'see red').
'end'+'anger'='ENDANGER'
'in' is the link.
(Other definitions for endanger that I've seen before include "Expose to injury or extinction" , "Put in trouble" , "Threaten" , "Place into peril, jeopardise" , "compromise" .)
