Jon Dadi Bodvarsson scored the equaliser as Millwall drew 1-1 with Queens Park Rangers at The Den in the Sky Bet Championship on Tuesday night.
The Icelander struck in the 70th minute to cancel out Ilias Chair's opener and ensure a share of the spoils.
Gary Rowett opted to field a 5-2-3 formation against The R's, with a front three of Jed Wallace, Troy Parrott and Mason Bennett starting - the latter coming back from injury to take his place in the XI.
Tom Bradshaw, meanwhile, returned to the bench.
The Lions, backed by 2,000 fans inside The Den once again, started the game on the front foot and had the first chance with six minutes played, but afer Bennett laid the ball off for Troy Parrott, his shot was saved by Sent Dieng in the QPR goal.
Shaun Williams then let fly from distance with 10 minutes on the clock, but his effort whistled just past the post.
A sustained spell of pressure from Rangers followed, with a number of corner-kicks forced, but that came to an end after Dominic Ball - who had earlier been correctly booked for simulation inside the penalty area - saw his effort saved by Bartosz Bialkowski.
From there, though, it was The Lions who pushed forward at the other end, and after a couple of fluffed attempts, Parrott was able to control Jed Wallace's pass and shoot, but he was denied by Dieng. A number of Millwall players, including Scott Malone, then tried to find a way into the area, but the attack was to come to a conclusion with the left-back firing over the crossbar.
Bennett's curling effort went just wide as The Lions attempted to take hold of the game shortly before the half-time break, with Ilias Chair then sending his own attempt from distance over as the half came to a close.
The second-half was eight minutes old when QPR took the lead. After the ball was cleared as far as Chair, he unleashed an unstoppable effort from outside the penalty area which gave Bialkowski little chance.
Shortly after, slack defending could - and perhaps should - have led to a second for Rangers, but Lyndon Dykes' attempt was well saved by Bialkowski.
Jed Wallace's corner was nodded wide by Bennett shortly after the hour-mark as The Lions attempted to get back into the game, and a triple substitution on 64 minutes saw Rowett shake things up in those attempts, with Bodvarsson, Ryan Leonard and Matt Smith all entering the fray in place of Alex Pearce, Bennett and Williams.
Bright Osayi-Samuel, however, was the next man to threaten in front goal, but as he broke into the far side of the penalty area, Bialkowski was quick to rush out and block behind. Shaun Hutchinson's ball then sent Mahlon Romeo away down the right-hand side, but after the right-back was able to cross, Bodvarsson's header went over.
Bialkowski and Chair's personal battle continued with 69 minutes on the clock, but this time the stopper saved well - Millwall, however, were able to equalise just a minute after as Bodvarsson struck home via a deflection to level the scores.
Malone received the ball on the left-hand side after good work from Smith with 12 minutes remaining, but his cross was headed over by substitute Bradshaw, before a Jed Wallace free-kick was the sent into the box, but Smith's tame header was gathered by Dieng.
As the game entered the latter stages and stoppage-time it was Millwall who were pushing for a winner, but referee Jared Gillett blew for full-time with the score level.
