Millwall manager Kenny Jackett refused to declare his side safe from relegation despite Alan Dunne's late winner giving the Lions a 1-0 npower Championship victory over 10-man Leicester at the King Power Stadium.
The visitors failed to make their numerical advantage count for 85 minutes following Wes Morgan's dismissal in a surprisingly even contest, until Dunne popped up to coolly slot home Richard Chaplow's cutback for his first goal in three years.
The win takes Millwall to 50 points, usually considered enough to avoid relegation, but Jackett insists there is still work to be done in the league before the Londoners can focus on their FA Cup semi-final against Wigan at Wembley.
"I think it's going to take more than 50 points," said Jackett, whose side have now gone six and a half hours without conceding a goal. "We're 50 points with nine games to go and we'd rather get safe sooner rather than later.
"We want to go into that game [against Wigan] with good form, some confidence and playing well.
"I've thought for a little while that 50 points won't be enough to keep you up. It does look like every club at the bottom is going to fight to the end. Fifty points is something that you look for but we're on 50 points with nine games to go so if we finished on that I'd be very disappointed."
Leicester boss Nigel Pearson was left to rue a sixth straight game without a win as his side's promotion hopes continue to crumble.
There were no complaints about Morgan's sending off; referee Stuart Attwell was left with little choice after the Foxes captain bundled over Andy Keogh with only three minutes on the clock.
"I could bemoan a number of things but I think it's pretty unfortunate tonight," said Pearson. "The players have worked very hard to get something out of the game and to concede a goal so late is, I think, quite cruel. I don't think the players deserve that tonight.
"The players have shown a lot of desire to play in a positive fashion despite going down to 10 men. It's not going for us at the moment but we've got to keep working hard."
