Don raised tennis umpire's call? (3,2)

Ross

I believe the answer is:

not up

'tennis umpire's call?' is the definition.
(tennis term)

'don raised' is the wordplay.
'don' becomes 'puton' ('put on' can be a synonym of 'don').
'raised' says the letters should be written in reverse.
'puton' written backwards gives 'NOT UP'.

(Other definitions for not up that I've seen before include "with tennis call" , "still in bed" , "call in court" .)

I've seen this clue in The Telegraph.
