Neil Harris equalled Teddy Sheringham's league goalscoring record as Millwall ground out a hard-fought point against Cardiff.
The visitors twice went ahead through Gary O'Neil and Alan Lee, but Neil Harris and Jo Tessem each opened their accounts for the season.
O'Neil, a lifelong Millwall fan on loan from Portsmouth, had opened the scoring by capitalising on David Livermore's mistake in the 39th minute to coolly slot past Graham Stack.
But Millwall hit back immediately after the break through Jo Tessem, who ran on to substitute Harris' cross to fire in from ten yards.
Alan Lee put Cardiff ahead in controversial fashion in the 68th minute when he appeared to drag defender Darren Ward down to head in from close range.
The goal brought howls of protest from the Millwall players, but they needn't have bothered, because they were only behind for another six minutes.
Harris rose to head in Kevin Muscat's long cross to head in his first of the season, and the 93rd league goal of his career to equal Sheringham's haul.
Lee forced tempers to again flare in the Millwall penalty box late in the match when he hacked Stack to the ground, sparking a 20-man scuffle in the area.
If only Cardiff had shown the same amount passion in the first half. Every time Lennie Lawrence's side looked to be going on the offensive, they were broken down by the industrious Jody Morris and Dennis Wise in the centre of midfield.
Millwall started the better of the two sides, and Barry Hayles came close to an opening in the fifth minute when he was fed from the left by bandy-legged winger Josh Simpson, but was hustled off the ball by Darren Williams.
And he should have done better on the hour when his tame shot from eight yards dribbled wide of the post.
Ward forced Warner into a point-blank save in the sixth minute when he met Wise's corner. Then the defender, yet to score this season for Millwall, was handed another chance when he shaved the post off another corner from his manager.
Chris Barker, who had lost his marker Ward for the defender to break clear early in the match, made up for his error in the 10th minute when he blocked Alan Dunne's fierce shot.
Tessem, on loan from Southampton, was unlucky in the 27th minute when he opted to shoot from at least 30 yards out, and his effort flew past Warner wide of the post.
But the half-time substitution of Harris for Simpson paid dividends when the striker - beginning in an unfamiliar left wing role before moving to the centre later in the match - put through for Tessem's first goal for Millwall.
