Newcastle’s men’s, women’s and under-21 sides will wear black armbands during their pre-season matches to honour Keegan, who guided the club to Premier League promotion in 1992-93 and second place in the 1995-96 top flight.
A minute’s silence will be observed before Eddie Howe’s side play Gateshead in an away friendly this Saturday.
Keegan’s photo will be displayed on screens at St James’ Park in the seventh minute – a reference to the number seven shirt he wore as a player – when the men’s side face Bayer Leverkusen and Strasbourg on 15 and 16 August.
The same tribute will take place when the women’s team face Inter Milan on 16 August, giving supporters the chance to join a minute’s applause for the former England captain and manager.
Newcastle said they will consult Keegan’s family on plans for a permanent tribute.
In June, Keegan had revealed he had stage four cancer, which is the most advanced stage of cancer and means the disease has spread to other parts of the body.
His family initially disclosed he was battling the disease in January.
A statement on behalf of the Keegan family this week said he was “surrounded by his wife and daughters in his final moments”.
During an illustrious playing career, he also enjoyed spells at Scunthorpe United, Hamburg and Southampton before managing Newcastle, Fulham, England and Manchester City.
