Goalkeeper Joe Murphy was the hero for Scunthorpe as they drew at home with 10-man Leicester.
Murphy produced a superb save to keep out Foxes striker Matty Fryatt as the home side failed to take advantage of Iain Hume's second-half dismissal.
Hume was sent off for a second bookable offence after going in with a high foot on home defender Cliff Byrne.
Leicester defender Patrick Kisnorbo had a goal disallowed for offside before Murphy produced his fabulous block.
Scunthorpe manager Nigel Adkins:
"Maybe it's a sign of how far we've come when we're is disappointed we haven't beaten a Leicester side with the millions of Milan Mandaric.
"I think we forced the issue all the way through the game to try and win it.
"We've kept good possession of the football We didn't put the ball into the penalty area as well as we could."
Leicester coach Gerry Taggart:
"It's not a sending off. Iain has jumped early for the ball and accidentally caught the guy who I think has made a meal of it.
"We have all seen the replay of Patrick's goal in the dressing room and he is clearly not offside.
"Officials don't have an easy job, but we all know but he was clearly onside."
