Aston Villa fans will be targeted in a new campaign to get more people registered to help blood cancer victims.
Anthony Nolan is now working with Aston Villa Football Club after club captain Stiliyan Petrov was diagnosed with leukaemia.
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.
Recruitment takes place at the Aston Villa Academy from 11am to 2pm. Volunteers from Moseley Round Table will man the stall.
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.
