Britain's Paula Radcliffe has been registered to run in Friday's 10,000m at the Olympics just days after pulling out of the marathon.
She was among the names listed to compete when entries were submitted on Thursday.
But Radcliffe can still withdraw, and is not certain to take part.
"It's now up to her whether she runs, but she does have the opportunity to pull out at any time before the race," said athletics team leader Max Jones.
Radcliffe, 30, is believed to have made a full physical recovery after dropping out of Sunday's marathon, run in the searing Athens heat.
And British Olympic Association chairman Craig Reedie indicated he would like to see her take part in the 10,000m.
"I don't think the heat in Athens over the last few days has been nearly as bad as expected," Reedie told BBC Five Live.
"The evenings are actually quite cool in the stadium.

"If she feels up to it, I would hope she runs and she performs to the very, very high level that she normally does."
Jones confirmed Radcliffe had been entered for the race, but this was merely the confirmation of original selections.
"I don't know what her intentions are, the decision will be hers and no one elses," said Jones.
"Paula trained twice yesterday and she'll know better than me what kind of state she is in."
On Monday, in a tearful BBC interview with Steve Cram, Radcliffe insisted she would wait before making a considered decision.
"I desperately want to get out and redeem something, but I'm not going to put myself in the arena if I'm not right," Radcliffe said.
"Part of me wants to do it, but part of me does not want to put myself through it again.
"My plan was to win the marathon and decide after that."
I hope she does run.
