I'm just off to Newcastle General Hospital to visit Harvey Gaydon, the 14-year-old Darlington boy who's had a bone marrow transplant.

Harvey, who is suffering from his second bout of leukaemia, is in an isolation unit for up to eight weeks while he waits for the new cells to start working.

TFM Radio presenter Graham Mack, who was recently chosen as a bone marrow match, is coming up as well to wish Harvey well.

Graham is desperately waiting for the call to tell him he's needed for a bone marrow transplant which could save someone's life.

Together, we're trying to raise awareness of the need for more bone marrow donors.

Apparently, we'll be able to speak to Harvey via a telephone through a glass panel.

I'll let you know how he's doing when I get back.
