BURY moved up to 17th in League One with a hard-fought goalless draw at promotion-chasing Millwall.
In a game of limited opportunities, the Shakers continued their impressive defensive form by keeping their fifth clean in seven matches under new manager Lee Clark.
Goalkeeper Joe Murphy performed second-half heroics to deny Byron Webster and Lee Gregory.
Lions forward Steve Morison had a goal chalked out for offside as Millwall slipped out of the play-off places, while Bury moved four points clear of the drop zone.
Clark opted for experience after making two changes to the side that beat Bristol Rovers in their last match.
Teenage midfielder Callum Styles was replaced by Jacob Mellis, who returned from a foot injury.
Veteran striker Ryan Lowe was also recalled to the starting line up in place of Tom Pope.
The Shakers were pinned back in the opening 10 minutes but dug deep to withstand some heavy Millwall pressure.
Chances were few and far between but Jed Wallace came the closest for the Lions with a volley that looped over the bar.
Bury grew into the game and enjoyed long periods of possession.
But they were dealt a blow when midfielder Andrew Tutte was forced off through injury, with Manchester City loanee Kean Bryan introduced as his replacement.
A midfield trio of Paul Caddis, Mellis and Bryan moved the ball well and began to dictate the game as the Shakers gained control.
James Vaughan peeled off his marker in the 25th minute to break through on goal but a fantastic last-ditch tackle from Lions skipper Tony Craig denied the forward.
Morison prodded an effort wide late in the first period but the Shakers comfortably saw the game through to half time unscathed.
Millwall were quickest out of the blocks in the second half as Wallace brought the best out of Murphy with a fierce drive.
But again Bury showed their resolve to grapple back control.
Caddis popped up on the edge of the box to test Lions stopper Tom King before Vaughan lashed a volley over the bar.
The hosts thought they had opened the scoring in the 67th minute when Morison finished off a swift counter attack but it was ruled out for offside.
Millwall cranked up the pressure in the closing stages but they struggled to find a way past the impressive Murphy.
The Bury stopper made a stunning save to keep out Webster’s header before showing magnificent reflexes to keep Gregory at bay.
The hosts pressed for a winner late on but Bury stood strong to keep a third consecutive clean sheet, with 35-year-old Murphy earning his sixth in nine appearances since joining on loan from Huddersfield.
