A second tie put on where actors perform (6)
I believe the answer is:
replay
'a second tie' is the definition.
(tie can mean a sporting fixture)
'put on where actors perform' is the wordplay.
'put' becomes 'lay' (synonyms).
'on' is a charade indicator (letters next to each other).
'where actors perform' becomes 'rep' (short for repertory theatre).
'lay' put after 'rep' is 'REPLAY'.
(Other definitions for replay that I've seen before include "Repeated match" , "Second showing?" , "Match held again" , "second game" , "A restaged match" .)
