Britain's marathon team for the World Athletics Championships in Osaka has been announced but does not include Paula Radcliffe at this stage.
The women's world record holder, 33, has recovered from recent back problems and is currently training in the US.
She could yet decide to compete in the marathon in Japan as the defending champion, or revert to the 10,000m.
A UK Athletics spokesman said officials are in an "ongoing dialogue" with the ex-London and New York Marathon winner.
In Radcliffe's absence, the British team is headed by Jon Brown and Mara Yamauchi.
