Ulster Rugby and Ballynahinch Rugby Club will open books of condolence.
At Ravenhill on Sunday, fans were laying floral and other tributes in memory of young Ulster star Nevin Spence both outside and inside the ground.
The 22-year-old died alongside his father, Noel and elder brother Graham, in a tragic farm accident on Saturday night.
Ravenhill will be open from 10am to 5pm daily for fans and friends of Nevin to pay their own personal tributes and sign a book of condolence.
Meanwhile, Ballynahinch Rugby Club, where both Nevin and Graham were players, are also to open a book of condolence on Monday evening.
The club at Ballymacarn Park will be open from 6pm-9pm daily for anyone who wishes to pay tribute in anyway to the memories of Noel, Graham and Nevin.
