Eilish McColgan will hear in the next 24 hours whether she has been included in the British team for this month's world championships in the Korean city of Daegu.
However, the 20-year-old might have to decline the invite if her worst fears are realised when she undergoes scans on an ankle injury sustained during the latter stages of her 3,000 metres steeplechase race at the Aviva Grand Prix at Crystal Palace on Saturday.
Prostrate and in agony on the track at the finish, the fact that the initial prognosis was a fracture added even more lustre to the 20-year-old Dundonian's performance. Her time of 9 minutes and 44.8 seconds lowered her existing Scottish and UK under-23 records. It could, and surely would, have been much lower if her ankle had not given out on the final water jump, forcing her to battle through the pain to cross the line.
"I had an entire lap where my ankle was sore and that's why it looked like I was dying at the finish," revealed McColgan. "I definitely would have run under 9:40 but my ankle was buckling on every jump I did. I'm just so disappointed because I think I would have had the A standard."
It should still suffice, health permitting. However, Lee McConnell likely removed any doubts over her presence in the individual 400 metres in Daegu by delivering her quickest time for nine years to claim top spot in the UK rankings. In a race won by Sanya Richards-Ross, the Scot took fifth place in 51.01 seconds and will surely now get the nod, even if the UK Athletics selectors opt to gamble on the inclusion of Olympic champion Christine Ohuruogu whose poor form was highlighted as she trailed in last.
Meanwhile, American Walter Dix said Olympic and world champion Usain Bolt could "definitely be beaten" in South Korea after easing to victory in the 200 metres.
Dix was among a number of US athletes to record impressive wins on the second day of the meeting, with fellow sprinter Carmelita Jeter and Richards-Ross also laying down the gauntlet to their rivals ahead of the worlds in Daegu.
Olympic double bronze medallist Dix clocked 20.16 seconds into a minus headwind and was pleased by his performance. "All I do is win, that's why you can never count me out. I need a couple of medals at the world championships and people will start to look out for me," said Dix, the US champion at 100 and 200.
Bolt may not have been at the meeting, which he also missed last year because of British tax rules on promotional earnings, but he will be the man to beat in Daegu.
Another sprinter to watch at the worlds will be Jeter, who has been in consistent form all season and, aged 31, will be a strong contender for a first global title after bronzes in 2007 and 2009. The second fastest woman of all-time over 100m - only the late Florence Griffith-Joyner has gone quicker - powered down the straight to win in 10.93, ahead of Trinidad & Tobago's Kelly-Ann Baptiste (10.97) and Olympic and world champion Shelley-Ann Fraser Pryce (11.10).Home favourite and world and European triple jump champion Philips Idowu was upstaged by American Christian Taylor, who smashed his personal best by 28 centimetres with a third round leap of 17.68 metres to take victory. The always colourful Idowu, his cropped hair dyed blonde with a blue stripe down the middle and resplendent in white headband and knee-high white socks, was far from his best and had to settle for third with a jump of 17.07.
In other events, Australian Sally Pearson scorched to victory in the women's 100m hurdles, Puerto Rican Javier Culson won the men's 400m hurdles in a season's best 48.33 seconds and Lithuania's Virgilijus Alekna, twice Olympic and world discus champion, secured victory with a throw of 66.71 metres.
