Millwall have slipped into the relegation zone after their resistance was eventually broken by West Bromwich Albion at the Hawthorns.

Dwight Gayle grabbed the eventual opener before former Arsenal full back Kieran Gibbs added to the hosts’ lead late into the second-half.

It means the Lions are now 22nd in the Sky Bet Championship table, with six points, after 10-man Reading claimed their second victory this season against Hull City.

Neil Harris reintroduced captain Steve Morison into the starting 11 after he was dropped to the substitutes' bench for Tom Bradshaw in the defeat to Queens Park Rangers during midweek.

Jiri Skalak, Mahlon Romeo, and Byron Webster were also given starts while the injured Shaun Hutchinson continues to miss out.

Millwall gave a good account of themselves against a side which were relegated from the Premier League in May for several periods.

Webster, who had a lengthy injury layoff, showed his value when he intercepted a threatening move from the hosts during the opening exchanges.

At the other end, Jed Wallace tried to find his way through the West Brom defence but fired over the crossbar.

He was at the back four again when he attempted from long-distance, however, Craig Dawson was there to clear with a header off the line.

But it was during the restart where West Brom showed their quality – Gibbs going close before Gayle broke the deadlock past the hour mark.

The lead was doubled just over 10 minutes later when Gibbs arrowed his shot into the far corner of the net past Ben Amos late on.

Wallace tried to support a resurgence when he setup substitute Aiden O’Brien, who replaced Skalak, but the ball was curled wide of Sam Johnstone’s goal.

Millwall have now lost five of their last six Championship games with this recent defeat, with one win in their opening nine fixtures.

Only Ipswich Town and Preston North End - who are level on five points each - are below them.
