Millwall stretched their unbeaten run in the Sky Bet Championship to three games on Saturday afternoon with a scrappy goalless draw at Deepdale against Preston North End.
In a game of few chances, Neil Harris' side defended resolutely against a Preston side offering little in attack to secure their second successive draw on the road.
The manager opted to keep the same squad of players that defeated Leeds United last Saturday together, with Fred Onyedinma maintaining his place up front in the absence of Lee Gregory.
The opening exchanges saw the hosts keep the ball for large periods without threatening Jordan Archer, but the first chance of the game went the way of The Lions as on 13 minutes, George Saville forced Chris Maxwell into a smart save.
On 16 minutes, Tom Barkhuizen called Archer into action for the first time, as the attacker's effort had to be palmed away for a corner-kick by the Scot.
As the half-hour approached, Millwall were able to limit Preston to attempts from distance - Darnell Fisher and Joshua Harrop blazing well over the crossbar.
On 53 minutes, a neat move by the home side saw Harrop nearly open the scoring, but the former Manchester United man got the ball stuck underneath his body as he slid in - James Meredith promptly cleared behind for a corner-kick.
In a game of few clear-cut chances, Wallace fired wide on the hour-mark. With 75 minutes on the clock, Wallace and Saville combined, but the latter's shot looped over the bar.
Millwall piled forward on 87 minutes, but Wallace's cross was stopped by the PNE defence with a handful of Lions waiting to tap home in the penalty area. Saville also tried his luck from distance but found the arms of Maxwell.
After six minutes of stoppage-time, referee Mr Bond blew time on a match that saw The Lions gain a valuable point away from home.
