Darius Henderson scored his seventh goal in three games late on to earn Millwall a replay against Championship counterparts Southampton in the FA Cup fourth round this afternoon.
Henderson's poked effort four minutes from time was his 16th of the season and cancelled out Ricky Lambert's first-half strike.
Early on it was Millwall, struggling in the league, who made the running with Liam Feeney striking the post after just two minutes before Harry Kane and Henderson missed further chances.
Lambert notched his 18th of the campaign by bulleting a header past David Forde after good work on the left from Dan Harding.
The Saints looked set to progress to round five before Henderson's low effort made its way past Bartosz Bialkowski.
Both sides will eagerly await the draw for the fifth round, which takes place at around 3.40pm tomorrow.
