Homeric quote you cut short in ring with heavyweights (5)

'ring with heavyweights' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'homeric quote you cut short' is the wordplay.
'homeric quote' becomes 'doh' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cut short' means to remove the last letter.
'you' with its last letter removed is 'yo'.
'doh'+'yo'='DOHYO'

'in' acts as a link.

Can you help me to learn more?
