Distract team on circuit (9)
I believe the answer is:
sidetrack
'distract' is the definition.
(I've seen this before)
'team on circuit' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'on' means one lot of letters go next to another.
'circuit' becomes 'track' (synonyms).
'side'+'track'='SIDETRACK'
(Other definitions for sidetrack that I've seen before include "Divert" , "Bit of railway" , "Provide diversion" , "draw away" , "lead away" .)
