Poor side away from home fails to survive (4,3)

I believe the answer is:

dies out

'fails to survive' is the definition.
(I've seen this before)

'poor side away from home' is the wordplay.
'poor' is an anagram indicator.
'away from home' becomes 'out' (synonyms).
'side' anagrammed gives 'dies'.
'dies'+'out'='DIES OUT'

(Another definition for dies out that I've seen is " fails to survive".)

I've seen this clue in The Guardian and The Globe and Mail.
