Roy Keane will captain a team of United legends, including Ryan Giggs, Rio Ferdinand, Paul Scholes and Gary Neville, against a combined Celtic and Republic of Ireland team in Cork.
The charity match, which will be played in front of a sell-out crowd of 45,000 fans at Pairc Ui Chaoimh, has been arranged as a tribute to Miller, who passed away in February this year at the age of 36.
Kick-off is at 15:00 BST and the game be will be broadcast live globally on our YouTube and Facebook pages. Sky customers in the UK and Ireland can also watch it for free on channel 418, without subscribing to MUTV.
