• The Court of Arbitration for Sport (CAS) has announced that it will delay a decision on Maria Sharapova’s appeal against a two-year ban issued by the International Tennis Federation (ITF) until 19 September. Sharapova, who will now miss the Rio 2016 Olympics, was issued with a two-year ban on 8 June after testing positive for meldonium. She immediately appealed.

• UEFA has announced that it collected 1,818 samples from players during the Euro 2016 tournament without a single adverse analytical finding (AAF). Of the total, 354 samples were collected in competition and 1,464 were collected out of competition. Samples included blood, urine and serum. Meanwhile, UEFA has dropped all disciplinary proceedings against Mamadou Sakho. The Liverpool player failed a doping test after the Europa League game against Manchester United on 17 March. UEFA did not explain why it had decided to drop the case.

• The International Association of Athletics Federations (IAAF) will allow Darya Klishina to return to competition, after it decided that the Russian long jump specialist had met the eligibility criteria to compete as a neutral athlete under Competition Rule 22.1A. The rule change amendments are available at the bottom of this PDF. An IAAF statement also revealed that it has rejected ‘most’ of the 136 applications under Competition Rule 22.1A(b), which allows athlete ‘not tainted’ by Russian anti-doping failures to compete in international competition.

• The Confederation of African Football (CAF) has announced that Christian Ngudikama of the Democratic Republic of Congo and Bryan Cottle of South Africa have both been issued with two-year bans for committing an anti-doping rule violation (ADRV). Ngudikama tested positive for Ephedrine at the 21 January group game against Angola in the African Nations Championship, which DR Congo went on to win. Cottle tested positive for methylhexaneamine at the 17 April game against Zambia in the Futsal African Cup of Nations.

• The Court of Arbitration for Sport (CAS) has rejected an appeal from Aslı Çakır Alptekin for a further reduction to an eight-year ban that has already been reduced to four years. In August last year, the CAS ratified a settlement agreement between the International Association of Athletics Federations (IAAF) and Alptekin to reduce an eight-year ban to four years. The IAAF had initially sought a lifetime ban for a second doping offence, after abnormal values were found in blood samples collected between July 2010 and October 2012.

• The IAAF Ethics Board has dismissed a challenge by three Athletics Kenya board members to an extension to their provisional suspensions. The IAAF provisionally suspended AK President Isaiah Kiplagat, Vice President David Okeyo (also an IAAF Council member) and AK Treasurer Joseph Kinyua for 180 days on 30 November 2015, which meant that their provisional suspension should have expired on 28 May 2016. However the suspensions were extended on 20 May 2016. All three are suspended due to allegations that they diverted sums paid to AK by Nike; that they accepted gifts from Qatar; and sought to suppress positive doping tests.

• The International Weightlifting Federation (IWF) has announced that three more athletes have returned adverse analytical findings (AAF) from the International Olympic Committee’s (IOC) retests of samples taken at the Beijing 2008 Olympics. Tigran Martirosyan of Armenia tested positive for stanozolol and dehydrochlormethyltestosterone; Sardar Hasanov of Azerbaijan tested positive for dehydrochlormethyltestosterone; and Sibel Özkan of Turkey tested positive for stanozolol. The three extra positives takes the IWF to ten positives from the 31 identified by the IOC from 454 Beijing 2008 samples reanalysed. The IWF also announced ten of 23 positives from the IOC’s retests of 265 samples taken at London 2012.
