Article in L'Equipe about a hybrid game (8)
I believe the answer is:
lacrosse
'game' is the definition.
(lacrosse is a kind of game)
'article in l'equipe about a hybrid' is the wordplay.
'article in l'equipe' becomes 'le' ('the' in French, as used in newspaper L'Equipe).
'about' means one lot of letters goes inside another.
'hybrid' becomes 'cross' (I've seen this before).
'a'+'cross'='across'
'le' enclosing 'across' is 'LACROSSE'.
(Other definitions for lacrosse that I've seen before include "Score's uncertain after the Spanish" , "Ball game using netted stick" , "Game played with netted sticks" , "Game played with nets on sticks" , "Like thirteen of the other clues in the French" .)
