Mo Farah is set to have his medical data analysed for evidence of doping in light of the allegations against his coach Alberto Salazar, the chairman of UK Athletics has confirmed.
Ed Warner also said he would advise Farah to steer clear of Salazar until the doping allegations against the American coach had been properly investigated, while adding that the governing body could break ties with the coach.
"What we can look at is all the data surrounding our own athlete, Mo Farah: blood data, supplements data - everything surrounding his medical treatment," Warner told the BBC. "We need to make sure there's nothing else there we haven't seen, we're not aware of, hasn't been analysed."
A investigation by the BBC and American investigative journalism group ProPublica accuses Salazar of using doping practices for his athletes at the prestigious Nike Oregon Project, where Farah is his star athlete.
While there is no suggestion of any wrongdoing by Farah, and Salazar denies the charges, the double Olympic champion is concerned about the damage to his reputation and withdrew from a Diamond League event in Birmingham on Sunday so he could return to the United States and "seek answers to my questions".
"It may well be that the outcome of our own investigation says there's nothing untoward going on as far as we can uncover in any way, shape or form around British athletics and a British athlete,'' Warner said.
"One of the possible outcomes of all of this is, even though - and I'm sure that's probably going to be the case - there's nothing untoward proven around Mo Farah and British Athletics, we might still recommend to Mo and might still decide ourselves to suspend our relationship (with Salazar) because of the reputational damage that could be caused. It's going to take time, but not a lot of time, I hope. I would think weeks, not months."
Salazar, who also works as an endurance consultant to UK Athletics, has been accused by his former assistant, Steve Magness, of violating anti-doping rules and encouraging doping by one of his top runners, Galen Rupp.
Rupp won the silver medal in the 10,000 metres at the London Olympics in 2012, finishing behind Farah. Rupp also denies any wrongdoing.
Farah has said he will not break ties with Salazar as there is no clear evidence against the American.
Warner added: "If I was a close mate of Mo's and he was asking me personally - not as the chairman of (UK) Athletics - 'What do you think I should do?' I might have been inclined to say, 'Do you know what? The easiest thing for you to do right now is to suspend that relationship, take a breather, see how it all plays out, run the circuit in the summer in Europe, on to the world championship in Beijing, and see what transpires.'
"It's a very fine decision. There are loyalty issues - nothing has been proven against Alberto Salazar.''
