Physio's work, as during rough games (7)
I believe the answer is:
massage
'physio's work' is the definition.
I can't tell whether this definition defines the answer.
'as during rough games' is the wordplay.
'during' is an insertion indicator.
'rough' indicates an anagram.
'games' with letters rearranged gives 'msage'.
'as' going into 'msage' is 'MASSAGE'.
Can you help me to learn more?
(Other definitions for massage that I've seen before include "Treatment by hand" , "Relaxing treatment" , "See 10" , "Rubbing of muscles" , "therapeutic treatment" .)
