RB Leipzig captain Willi Orban will have blood stem cells harvested on Wednesday after being found as a match for someone with blood cancer, the club said on Tuesday.

Orban, a Hungary international, has been training alone since Sunday after taking "special injections" to increase his stem cell count for the procedure. The club added that "it is unclear as to whether he can feature in the game" against Union Berlin on Saturday.

The defender has been registered with the DKMS (Germany's bone marrow donor registry) since 2017. The procedure, which in some cases also requires a bone marrow extraction, is used to treat people with blood cancers and disorders.
