• A distance runner has been sanctioned with a two year ban and a snooker player has been provisionally suspended, after both returned adverse analytical findings (AAF) on 17 November last year, Serbia’s anti-doping agency (ADAS) announced. Former national marathon champion Nenad Zivkovic (Ненад Живковић) was sanctioned with a two year ban after testing positive for tuaminoheptane and methylhexanamine. Snooker player Marko Stoilkovic’s (Марко Стоилковић) case has yet to be determined. 

• The Russian Athletics Federation (RusAF) sent the Athletics Integrity Unit (AIU) of World Athletics its explanation regarding charges issued to seven officials due to failure to cooperate with its investigation into ‘whereabouts’ violations committed by high jumper Danil Lysenko. RusAF announced it sent the explanation on the AIU deadline of 2 January, after an initial 12 December deadline was extended. RusAF maintains that Danil Lysenko asked Elena Orlova – one of the officials charged by the AIU – for help in translating Lysenko’s explanation for ‘whereabouts’ failures and his medical certificate, after which they were sent to World Athletics. RusAF contends that this translation process is what led to allegations of forged documentation. However, the AIU appears certain in its convictions, having spent 15 months investigating the case in cooperation with the Russian Anti-Doping Agency (RUSADA).

• Waterskier Samantha Dumala has been sanctioned with a public warning after failing to obtain a therapeutic use exemption for prohibited medication, the US Anti-Doping Agency (USADA) announced.
