Supporter of sport? (3)

Here is my best explanation:
This could be a double definition.
'supporter' is the first definition.
(I've seen this in other clues)
'sport?' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'of' acts as a link.
Can you help me to learn more?
