Mark Webster diagnosed with rare form of blood cancer

Former world darts champion and Sky Sports pundit Mark Webster has been diagnosed with a rare form of blood cancer.

Webster, who claimed World Championship glory on the British Darts Organisation (BDO) circuit in 2008, has not worked at a darts event for Sky Sports since February and has this week revealed why during a wide-ranging interview on Darts World's YouTube channel.

Welshman Webster discovered in January that he had a rare form of blood cancer called hairy cell leukaemia and has not worked since he started chemotherapy in February.
