This clue might be a double definition.

'supports' is the first definition.
(I know this)

'rugby players' is the second definition.
Although both the answer and definition are plural nouns, I don't understand how they can define each other.

Can you help me to learn more?

(Other definitions for props that I've seen before include "Forward types" , "forwards" , "Buttresses" , "Items used on stage" , "Set" .)

I've seen this clue in The Sun and The Mirror.
