Send on rugby player? (7)
I believe the answer is:
forward
I believe this is a double definition.
'send on' is the first definition.
(synonyms)
'rugby player?' is the second definition.
(forward is a rugby position)
(Other definitions for forward that I've seen before include "To the front" , "Onward" , "team player" , "Attacker" , "Straight ahead" .)
