Banned, as might be retired trampolinist? (3,2,6)
I believe the answer is:
out of bounds
'banned' is the definition.
(thesaurus)
'might be retired trampolinist?' is the wordplay.
I cannot really see how this works, but
'retired' could be 'out' (synonyms) and 'out' is located in the answer.
This explanation may well be incorrect...
'as' acts as a link.
Can you help me to learn more?
(Other definitions for out of bounds that I've seen before include "like an exhausted kangaroo?" , "taboo" , "lying beyond field of play?" , "Skipper so exhausted" , "Off limits" .)
