Nottingham Forest missed the chance to move out of the Championship drop zone as they failed to score for a fifth successive game in the goalless draw at fellow strugglers Bristol City.
Forest would have leapfrogged City with a victory.
But veteran home goalkeeper David James made two outstanding saves to deny Marcus Tudgay in each half.
City also had chances with Stephen Pearson, Martyn Woolford, Marvin Elliott and Albert Adomah going close.
Pearson saw an early effort deflected narrowly wide following good work by Nicky Maynard.
But the hosts' best chances came after the break.
Woolford sent a 25-yards effort wide and perhaps should have scored after getting on the end of Cole Skuse's cross when just six yards out.
Reds keeper Lee Camp also produced a superb double to parry Marvin Elliott's shot from the edge of the box and then block another effort from Adomah.
At the other end James did brilliantly to keep out Tudgay's half-volley and acrobatically tipped over a header from the same player.
The England keeper saved a long-range attempt from Radoslaw Majewski while Luke Chambers headed wide.
Dexter Blackstock, who was making his first start following a year out with a serious knee injury, also blazed a shot over in the closing stages while Lewin Nyatanga also fired over the bar.
But neither side could find a breakthrough meaning the Robins have now failed to beat Forest in the last 30 meetings stretching back to December 1974.
Bristol City manager Derek McInnes:
"We are disappointed not to have worked their keeper more, but it wasn't through lack of effort. Forest came for a point and worked hard to get it. We defended strongly and on the odd occasion when Forest threatened, David James showed why he has been a top goalkeeper for so many years. It is clear we could do with a more physical presence up front and that is something I need to address during the January transfer window."
Nottingham Forest manager Steve Cotterill:
"If it hadn't been for David James we might have won by three of four goals. I won't say what I called him as we were leaving the field. He has been magnificent today. Marcus Tudgay could easily be walking away with the match ball for scoring a hat-trick. We have failed to score again, but not through poor finishing. And there were a lot of positives for us."
