Millwall picked up a point from a goalless draw at West Bromwich Albion to consolidate their place in the Championship play-off places.
Baggies midfielder Adam Reach sent two efforts off target in the first half, while Brandon Thomas-Asante fired narrowly wide after the break.
Albion keeper Josh Griffiths then made two fine saves to beat away Tom Bradshaw's near-post header and parry over a stinging drive by Zian Flemming.
Thomas-Asante had a late chance blocked and a Tom Rogic strike was deflected wide for the hosts as Millwall climbed to fifth after Blackburn's defeat at Birmingham and established a four-point gap to the chasing pack.
