Scunthorpe boss Graham Alexander rued the slice of luck that saw the Iron's six-game winning run ended by a 1-0 defeat at Walsall.
Kieron Morris' 13th-minute strike took a wicked deflection off Scunthorpe midfielder Neal Bishop to fly past goalkeeper Matt Gilks and earn the hosts all three points.
Gilks saved a second-half Erhun Oztumer penalty to keep Scunthorpe in it but their only chance to rescue a point saw Clayton Lewis' late 30-yard rocket denied by Mark Gillespie's unorthodox save.
Alexander said: "Their goal took a massive deflection and we can't do anything about that really. It's a stroke of luck that's gone against us.
"Our chance late on was probably the same sort of distance, same sort of strike as their goal.
"Theirs takes a deflection and goes in the top corner. Ours go straight and the keeper saves it. These are little things that you need to go for you.
"It was a nothing game really but they got the break with the goal and it gives them something to protect.
"Second half, we played a lot better, much more on the front foot and got into some good positions but we didn't show the quality needed to get that goal.
"We tried to get bodies forward but we just didn't have the quality that we usually have - which is disappointing.
"The lads have been fantastic up to this point, with six league wins on the bounce, and we knew that couldn't go on forever but we still expect better from ourselves than we produced today."
Walsall recorded their third-straight league win to move into the top half of League One and boss Jon Whitney hailed the whole club for their efforts in beating the snow to get the game on.
Whitney said: "I was out on the pitch this morning with the ground staff, the club secretary and the director, all clearing the snow off the pitch, everybody was digging in together to get the game on.
"I think we should dedicate the win not just to the playing staff, but all staff at Walsall for getting the game on.
"I thought we were the better team. We limited them to one chance.
"If you limit a Scunthorpe team - with the goals they have scored this season - to one good chance, that shows the energy our lads put in.
"Everyone to a man averaged seven or eight out of 10, and you need to be at those levels against Scunthorpe. I thought we stood up to them and deserved the win.
"The reaction after we missed the penalty was really good - we could have felt sorry for ourselves but we didn't change the way we played."
