MILLWALL were dumped out of the FA Cup by a clinical Bolton side on a wet and windy afternoon at The Den.
The Lions went into their fifth-round tie against the Premier League strugglers full of confidence following an impressive display at Brighton in midweek, but Ryo Miyaichi's third-minute goal put them on the back foot early on.
The visitors were denied a second goal when Steve Mildenhall palmed away Tuncay's drive soon after, and while both Darius Henderson and Andy Keogh had shots on goal at the other end, Kenny Jackett's side rarely looked like scoring before half-time.
Indeed, Trotters defender Grétar Steinsson's slice onto the roof of his own net was the closest Millwall came to scoring an equaliser in the first period.
The Lions improved after the restart and should have levelled through Paul Robinson's header, but he could only divert Scott Barron's corner wide.
And Bolton capitalised when David Ngog drilled home from the edge of the area just before the hour mark to put daylight between the two sides.
Visiting goalkeeper Ádám Bogdán produced a smart double save to deny both Harry Kane and Henderson in quick succession, although referee Kevin Friend had already blown for a foul as Barron's cross came into the area.
Millwall now face Middlesbrough on Tuesday night as Kenny Jackett's side return to action in the Championship, where their priorities undoubtedly lie.
Millwall: Mildenhall, Dunne, Barron, Robinson, Lowry, Smith (Wright, 57mins), Kane (Henry, 79mins), Trotter, Keogh, Henderson, Feeney (Bouazza, 71mins).
Bolton: Bogdan, Steinsson, Muamba, Tuncay, Davies (Pratley, 86mins), Ricketts, Reo-Coker, Ngog, Miyaichi (Eagles, 77mins), Wheater, Ream.
