American football? (6)

I believe the answer is:

soccer

'american football?' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for soccer that I've seen before include "Informally, game" , "Association football" , "The beautiful game?" , "American football?" , "Roy Keane's game" .)

I've seen this clue in The Guardian and The Sun.
