Laura Muir is expected to abandon plans to double up at August’s IAAF world championships in London due to the foot injury that has hampered her preparations. It has been revealed that the double European indoor gold medallist will miss next weekend’s trials in Birmingham as she continues to rehabilitate a problem diagnosed following a racing trip to the United States last month.

However it is now probable that the 24-year-old will focus solely on chasing gold in the 1500 metres at the worlds, confirmed performance director Neil Black, rather than attempt to also compete in the 5000m.

“I think that is the most likely outcome, although there hasn’t been that final discussion that says ‘is that the case’,” he said. “Her plan was to run at trials next weekend and with that not happening that has changed thing, so there is only that one per cent uncertainty if mad things happen, You never know, but I think it is very unlikely.”

That will mean patience, he added, with Muir not expected to re-appear until the Anniversary Games in London on 9 July. “Laura had to have a period of time where she didn’t run, that’s over and she has now progressed her training up to almost normal level, so she has had to adapt,” Black underlined. “She is back into it. She is not getting any symptoms and therefore she has had a different approach for this time of the season.”

However Olympic medallist Dina Asher-Smith is set to make her comeback in Birmingham after four months on the sidelines. The European 200m champion suffered a broken foot during the indoor campaign but Black is confident that the 21-year-old is on track for a recovery.

"Obviously it's a big task for her as she is not going to know until she races and races repetitively,” he admitted. “But I've spoken to her and she is in high spirits and excited to be returning to competition. We're all going to wait with bated breath to see what happens."

It will also boost a 4x100 relay squad that failed to finish in Lille due a botched baton change with Daryll Neita admitting it may be difficult to repeat their bronze from Rio 2016 without her presence. “We have a really good rapport in the team,” she said. “We were the perfect team in Rio and we really do need Dina back.” Hopefully we will see her back on the track soon.”
