Wrestler order us back? (4)

Ross

I believe the answer is:

sumo

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

'wrestler' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?

'order us back?' is the wordplay.
'order' becomes 'om' (Order of Merit).
'back?' says the letters should be written backwards (I've seen 'backed' mean this).
'om'+'us'='omus'
'omus' back-to-front is 'SUMO'.

Can you help me to learn more?

(Other definitions for sumo that I've seen before include "Style of traditional Japanese wrestling" , "Japanese form of wrestling" , "Large Japanese wrestler" , "Japanese wrestling with big fat men" , "foreign form of fighting" .)

I've seen this clue in the Sydney Morning Herald.
