Chris Dagnall's bundled effort handed Scunthorpe a dogged 1-0 victory over in-form Nottingham Forest and a first npower Championship win at Glanford Park since August.
The 24-year-old put the Iron on course to their first win in 2011 by clattering home from close range.
After finding space in the area, Dagnall managed to hold off pressure from Forest full-back Chris Gunter before putting his side ahead.
Defeat for promotion-chasing Forest curtailed their 10-match unbeaten run and saw them miss the chance to move into second place.
The visitors missed a plethora of chances either side of the break and came closest through substitute Dele Adebola, whose header rattled the bar in the 74th minute.
But credit must go to the Iron, who clung on to claim a thoroughly-impressive victory which boosts their hopes of avoiding the drop.
