Millwall will wear a white shirt at home this weekend to help support Prostate Cancer UK (PCUK).
The Lions have been given permission by the Football League to change from their usual navy blue and white home kit to pure white as part of 'Heroes in White' day associated with the charity.
A number of Millwall players are also supporting the 'Movember' movement by growing moustaches for the charity and a portion of the sales of the shirts will also be donated.
Supporters of the south London club will be encouraged to wear white and there will be event t-shirts on sale with profits going straight to PCUK.
