The Reds will take to the pitch for a friendly at Deepdale on Sunday for the first time since the brothers tragically died in a road traffic accident in Spain.
Ahead of the 3pm BST kick-off, there will be a rendition of LFC anthem You’ll Never Walk Alone and the home club will lay a wreath alongside the away supporters.
A minute’s silence will be observed in Diogo and Andre’s memory and digital tributes will be displayed on the screen and across pitchside LEDs.
Both sets of players will wear black armbands.
Preston have also created a commemorative edition of the matchday programme that features written tributes to Diogo and Andre.
The match will be televised live on ITV in the UK, on LFCTV and streamed globally on All Red Video, with coverage there beginning at 2.15pm BST (full details on how to watch are available here).
A pre-match programme will be broadcast live from the stadium across LFC’s social media channels and YouTube until kick-off, when rights restrictions take effect.
