Team row? It could be a distraction (8)
I believe the answer is:
sideline
'it could be a distraction' is the definition.
(a sideline might distract you from your main job)
'team row?' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'row?' becomes 'line' (as in a row of things).
'side'+'line'='SIDELINE'
(Other definitions for sideline that I've seen before include "Subsidiary trade" , "hobby" , "Spare-time activity" , "Secondary activity" , "Activity outside one's main job" .)
