Colchester United U23s fell to defeat in their first game of 2019, as a goal in each half was enough for Millwall to pick up all three points.
The U's named a strong side with a number of players having enjoyed first team football in the last couple of years, but it was Millwall who took the spoils with a strong defensive display.
Former Brightlingsea Regent player Rob Harvey was the first to see a sight of goal, but lifted his shot from a narrow angle over the bar.
At the other end, Dean Ager pulled a shot wide of the near post, as the two teams looked for a breakthrough.
Whilst Barnes saved well at his near post on eleven minutes, he could do little to prevent the Lions getting ahead on 33 minutes.
The ball came out to the feet of Hanson, and he drilled a low shot into the bottom corner.
Millwall almost got a second seven minutes after the restart, as Barnes spilled Harvey's shot, but it dropped onto the post and the U's keeper was able to collect.
The Lions eventually doubled their lead on the hour mark, as Saunders-Henry reacted quickest when his penalty was saved to tuck home the rebound.
The U's chances were limited, although Ogedi-Uzokwe twice headed wide from corners when under pressure.
The visitors saw out the remaining time to pick up the win.
U's: D. Barnes, Agboola (Triallist 59), Kensdale, Forino, A. Barnes (Anderson 59), Chilvers (Charles 81), Wright, Dunne, Miller, Ogedi-Uzokwe, Ager
