Centre is replaced on the quiet (2,6)

Ross

I believe the answer is:

in secret

'on the quiet' is the definition.
(I've seen this in another clue)

'centre is replaced' is the wordplay.
'replaced' indicates an anagram.
'centre'+'is'='centreis'
'centreis' with letters rearranged gives 'IN SECRET'.

(Other definitions for in secret that I've seen before include "sub rosa" , "privately" , "behind closed doors" , "Confidentially" , "Not openly stated" .)

I've seen this clue in The Globe and Mail.
