Patent legend in US returned for end of rugby match (2-4)

I believe the answer is:

no-side

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

'end of rugby match' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for no-side that I've seen before include "End of a rugby game" , "Rugby full time" , "End of rugby match" , "time at Twickenham" .)

I've seen this clue in The Independent.
