Learning rugby version outside (9)
I believe the answer is:
erudition
'learning' is the definition.
('erudition' can be a synonym of 'learning')
'rugby version outside' is the wordplay.
'rugby' becomes 'ru'.
'version' becomes 'edition' (I've seen this before).
'outside' indicates putting letters inside.
'ru' placed within 'edition' is 'ERUDITION'.
(Other definitions for erudition that I've seen before include "Learnedness, scholarship" , "Learning, scholarship" , "Knowledge, learning" , "profound scholarly knowledge" , "State of learning or culture" .)
