However, his luck wasn't in and it was the London outfit who took the lead just minutes later.
Against the run-of-play, Rangers broke down the right, swift winger Wayne Routledge opening up the defence with an impressive cross which left the Iceland international with little to do for the opener.
Managerless Blackpool looked to respond immediately with David Vaughan and Campbell forcing good saves from Lee Camp in goal.
After half-time, Rangers remained on top and when Blackpool stalwart Ian Evatt lunged out at Helguson there was no doubt as the referee pointed to the penalty spot.
Helguson stroked his spot-kick straight down the centre to open up a comfortable lead.
With just under 20 minutes to play, Seasiders' defender Stephen Crainey limped off to leave the home side a man down and it was all over bar the shouting as substitute Hogan Ephraim crashed a shot past a helpless Paul Rachubka in injury time to make it a comfortable win for Paulo Sousa's men.
