Put back in check, say (9)
I believe the answer is:
reinstate
'put back in' is the definition.
(I've seen this before)
'check say' is the wordplay.
'check' becomes 'rein' (both can mean to control or limit).
'say' becomes 'state' ('state' can be a synonym of 'say').
'rein'+'state'='REINSTATE'
(Other definitions for reinstate that I've seen before include "Restore to a former position" , "Put back into office" , "Put back in place" , "Restore to previous state or rank" , "Re-establish" .)
