Murphy provided the ball for French striker Romain Vincelot to tap home as Coventry went to second place on the League One table.
The on-loan Norwich City midfielder has been in solid form at the Ricoh Arena in the early part of the season, providing a number of assists and firing in an absolute thunderbolt a fortnight ago against Walsall.
Murphy took to Twitter after to the game to pay tribute to Coventry's supporters.
The grind was real today! Great from the boys!! @Coventry_City fans were out in force today #PUSB
