Sheffield United rescued a point with a 2-2 draw at Colchester thanks to David Carney's second Blades' goal in a week.
Luton Shelton claimed his first league goal for the Blades on 46 minutes but Kevin Lisbie levelled on the re-start.
Bottom-dwelling Colchester took the lead again when Johnnie Jackson's free-kick deflected off Chris Armstrong and past Paddy Kenny for an own goal.
But the lead was short-lived as Carney, who also scored in the 1-1 midweek draw with Watford, saved his side's blushes.
Colchester boss Geraint Williams:
"The game could have gone either way but I felt if any team was going to win it, it would be us.
"I think some of the football we played was some of our best of the season. We showed confidence and belief and I was delighted to see the lads so positive.
"But we've been punished for a mistake and that's what happens this season."
Sheffield United manager Bryan Robson:
"Things didn't go for us but there were a few good displays and I can't ask any more from my players.
"The players are behind me and I don't feel under pressure. We're not winning games we deserve to win and we're not killing teams off when we are able to.
"It's a forward-thinking club and we can keep on getting better and better."
