Promotion-chasing Brentford were held to a goalless draw by Scunthorpe.
The relegation-threatened home side started well with Jon Parkin dragging a shot wide and Michael O'Connor flashing a volley over the bar.
Parkin, on loan from Cardiff, should have given Scunthorpe the lead but hit the bar with a close-range header in the second half.
Brentford substitute Gary Alexander almost snatched victory late on but he drove his effort over the bar.
VIEWS FROM THE DRESSING ROOM
Scunthorpe assistant manager Chris Brass told BBC Radio Humberside:
"I'm a little bit frustrated but I was quite happy with the way that we scrapped and we have given a performance.
"I just thought that we did the ugly bit right, it was just the top bit we was slightly lacking.
"We're thankful that we haven't got any injuries, we can get rested up and the extra day will probably help us. We've got to keep believing, we're not playing terribly."
Brentford boss Uwe Rosler told BBC London 94.9:
"A few weeks ago we would have lost that match, we took the momentum from Monday into today, the pitch was horrible but I think the pitch was to our disadvantage and the direct style of Scunthorpe.
"The back four were ruthless and stood up to the physical challenge and in my opinion we had the biggest chances of the game.
"I was happy, as we knew it would be tough today, but a point is a good result."
