Millwall 5 Dagenham & Redbridge 0

Striker Darius Henderson shook off a hip injury and bagged a hat-trick to send Millwall through to round four of the FA Cup at Daggers expense.

Henderson had missed the previous two games, including the original third round tie, which ended goalless at Victoria Road.

But the 30-year-old was back with a bang to end Daggers run in their third consecutive replay of the competition and send the Lions through to face Championship leaders Southampton.

Manager John Still made two enforced changes to his starting line-up with Cristian Montano (ineligible under the terms of his loan) and Brian Woodall (groin) replaced by Richard Rose and Danny J Green.

And they got off to the worst possible start, conceding on seven minutes when Harry Kane’s weak shot found its way through to Henderson, who fired past Chris Lewington.

The goal settled any potential Millwall nerves after Saturday’s 6-0 hammering against Birmingham and they dominated first half proceedings.

The lively Kane, on loan from Spurs, was twice denied by Chris Lewington, but got the goal his work-rate deserved on 41 minutes.

Dominic Green conceded possession midway inside his own half to Liam Trotter, who raced forward and squared for Kane to fire low past Lewington.

It took until the final minute of the first half for Daggers first attempt at goal, but Richard Rose’s shot from the edge of the box failed to test keeper David Forde.

John Still shuffled the pack at half time, in a bid to get Daggers into the game. Striker Rob Edmans, making his first appearance since his summer move from Chelmsford, replaced Ahmed Abdulla and the visitors switched to 4-4-2 with good effect.

Playing with a far greater presence in attack, there were chances for Jon Nurse, Danny J Green and Dominic Green, but the trio failed to hit the target.

But the Lions finally sealed their progress with a three-goal blitz midway through the second period to stun Daggers.

On 59 minutes Kane’s excellent reverse pass played Hamer Bouazza through on goal and he squared to Henderson for a tap-in.

Three minutes later Henderson completed his treble. After Kane had been tripped by Rose in the box, the former Sheffield United and Watford striker made no mistake from the penalty spot.

And it got worse still for Daggers, who could not cope with Millwall’s movement all night and conceded a fifth on 65 minutes.

Bouazza’s deep cross from the left was headed back across goal by Henderson and finished from close range by Kane.

There were half chances for Scott Doe and Edmans to restore some pride, but neither was able to find the net, as Daggers bowed out.
