Terry Palmer put a dominant Rovers in front on 67 minutes when heading home after Shane Robinson knocked a Keith Doyle corner back across goal.

But Murphy latched onto Mark Clifford’s through ball to fire Blues level from a tight angle on 72 minutes.

Rovers' Stephen Grant was then shown a straight red card for a bad tackle on Dave Mulcahy within three minutes.

Murphy then hit the winner with a stunning dipping volley with just a minute to go.
