A strange team game, recalled layman (7)
I believe the answer is:
amateur
'layman' is the definition.
(thesaurus)
'a strange team game recalled' is the wordplay.
'strange' indicates anagramming the letters.
'game' becomes 'ru' (rugby union).
'recalled' is a reversal indicator.
'ru' reversed gives 'ur'.
'team' with letters rearranged gives 'mate'.
'a'+'mate'+'ur'='AMATEUR'
(Other definitions for amateur that I've seen before include "One is not professional" , "Fancier" , "Person who does something as a pastime rather than a profession" , "Unpaid (sports)" , "Dabbler" .)
