sevens

I'm a little stuck... Click here to teach me more about this clue!

This could be a double definition.

'figures in rugby' is the first definition.
'sevens' can be an answer for 'rugby' (I've seen this before). I am unsure of the 'figures in' bit.

'football' is the second definition.
(I know that sevens is a type of rugby union)

Can you help me to learn more?

(Other definitions for sevens that I've seen before include "Form of Rugby Union" , "77" , "rugby competition" , "Card game; form of rugby" , "Numbers" .)

I've seen this clue in the Evening Standard.
