Scottish treble winners Celtic will help Sunderland mark the 20th anniversary of the Stadium of Light next month.
Brendan Rodgers' men will head south on Saturday, July 29 for a pre-season friendly on Wearside – the first to be staged there since 2008 – to contest the Dafabet Cup.
The game will also mark the 50th anniversary of Celtic's 1967 European Cup triumph and members of the Lisbon Lions team have been invited to attend.
Sunderland ambassador Kevin Ball, who captained the club against Ajax in the opening fixture at the stadium on July 31, 1997, said: "To have Celtic here to celebrate the 20-year anniversary, almost to the day, will be a very special occasion for everyone involved with Sunderland AFC.
"The two sets of fans share the same principles of loyalty and passion for their clubs and both teams have long and proud histories.
"It's fantastic that Celtic have accepted our invitation to share this memorable day in what is also a very special year for them with the anniversary of the famous victory in Lisbon.
"I have no doubt it will be a great game in front of a full house and something both Sunderland and Celtic supporters will really love."
