The tie will take place during the week commencing Monday, 7th September 2026, with the exact date and kick-off time to be confirmed.

It'll be United's first ever visit to the Lions' current stadium - now known as The Den, formerly The New Den - which opened in 1993 and their second meeting in this competition. Millwall were 2-0 winners on Tyneside in the 1977/78 season.

Newcastle - Carabao Cup winners in 2025 - beat West Bromwich Albion 3-2 on Wednesday night, while Millwall edged past Queens Park Rangers on penalties after a 1-1 draw in the first round, then won 1-0 at Cambridge in the second round.

They currently top the Championship table with two wins from two games.

Ticket information will be released in due course.
