Paddy Madden's 41st-minute goal has given Scunthorpe United a 1-0 lead at half time against 10-man Gillingham.
Doug Loft was shown a straight red card for leaving the floor with both feet when lunging into a tackle on Luke O'Neill 10 minutes before the break.
The visitors made their numerical advantage count when Madden profited from a couple of defensive slips to take it around the keeper to give his side the lead.
Gillingham boss Peter Taylor was then sent to the stands at the death of the half after protesting too fervently to the fourth official.
Earlier in the half, Rory Fallon somehow managed to blaze over the bar from around three yards after he'd got himself on the end of a cross.
