Aston Villa fans will be targeted in a new campaign to get more people registered to help blood cancer victims.
The charity hopes to get men aged between 18 and 30 signed up to its register as they make the best donors, but only account for 12% of the current register.
Stiliyan Petrov, who joined Villa in 2006, was diagnosed with leukaemia, a form of blood cancer, in March.
As part of Support Stan - Register and Run, Villa will host a recruitment event at the stadium on May 6, when they face Spurs in their last game of the season. Fans can join the register by filling out a short form and providing a small saliva sample.
The support for Stan has been overwhelming and anyone who signs up to the register could potentially save a life. I hope that fans take advantage of this opportunity to make a difference in combating leukaemia."
Recruitment takes place at the Aston Villa Academy from 11am to 2pm. Volunteers from Moseley Round Table will man the stall.
"We particularly need young men aged 18 to 30 to sign up. We'd like to show fans that even though they can't help Stiliyan, they could help save the life of someone like him."
Aston Villa is working with Birmingham-based Cure Leukaemia and it is offering fans the chance to sign up for a fun run taking place at Sutton Park on May 27.
