Ten-man Notts County struck late to prevent Sheffield United from going third in League One.
Magpies fans, some of whom had helped clear the pitch of snow before kick-off, saw their side trail after just two minutes when Harry Maguire nodded in Nick Blackman's corner.
Francois Zoko was sent off for County when he was shown two yellows for a prolonged protest against a free-kick.
But Alan Judge levelled 10 minutes from time with a glancing header.
The home side, however, are now seven games without a win in all competitions, while the Blades remain fifth in the table.
VIEW FROM THE DRESSING ROOM
Notts County manager Keith Curle told BBC Radio Nottingham:
"There's a lot of players in there who know we could have had a very positive result today. A player's ill discipline has cost us.
"I've never known a referee change his decision because a player shouts or screams or says derogatory words to him or his linesmen.
"They're not going to turn round and say, 'Oh, you might be right'.
"He's got to learn from it. I thought the referee had a very good game today."
Sheffield United manager Danny Wilson told BBC Radio Sheffield:
"Having our nose in front and having a numerical advantage, we didn't do anything near enough in the second half to make the game more comprehensive.
"In the first half we had a good tempo. We didn't in the second and we've let them back in the game.
"There's a nervousness about us at the moment. Whether that's because of the pressure that's on us, I don't know.
"We are certainly not as good as we were as the first part of the season, but we'll get there."
