British athlete Jo Pavey has admitted her "emotions are all over the place" after learning that she could be retrospectively awarded a bronze medal from the 2007 World Championships.
The Turkish Athletics Federation issued a statement on Thursday confirming that Elvan Abeylegesse, who won a 10,000m silver medal in Osaka, has been requested to provide a defence regarding her sample, which was recently retested.
Abeylegesse is among the 28 athletes under investigation for doping after samples from the 2005 and 2007 World Championships were recently retested.

Responding to the news, Pavey said on her official Twitter account: "Elvan Abeylegesse rumour now confirmed by Turkish federation. My emotions are all over the place. Thank you for all the nice messages."
If Abeylegesse is subsequently stripped of her medal it would mean Pavey, who finished fourth in the race in Japan, would be upgraded and earn the first World Championship medal of her career.
Pavey, who was crowned European champion last year at the age of 41, thought she missed her best chance to claim an elusive world medal when she was passed by American Kara Goucher - who won bronze - on the home straight in Osaka.
She admitted a retrospective medal would not quite make up for the excitement of being rewarded for her achievement on the podium.
Pavey tweeted earlier this week:
Meanwhile Goucher tweeted a photograph of her bronze medal with this message:
Ethiopian-born Abeylegesse, 32, is still competing but has been withdrawn from this month's World Championships in Beijing.
TAF president Fatih Cintimar had said in a statement: " 'With sadness we have learned that the IAAF have asked for the defence of Elvan Abeylegeese regarding the retest of her 2007 sample. We will provide the public with further information after our own process.''
