I think there is more to the story than just an ankle injury.
Apart from DL Doha E. Manangoi has run 1500m times far under his normal level this year. Reportedly due to another injury in the early DL season which injury has kept him away for he rest of the season..
But he is not the only Kenyan top runner who has been underperforming recently:
His younger brother George ran PB 3:31.49 in DL Monaco but only narrowly got the third place for Doha at the Kenyan trials last week with a time around 6 seconds slower.
And the other Kenyan DL runners Bethwell Birgen, Vincent Kibet and Charles Simotho all ran far slower than their SB´s at the same trials (9, 5 and 5 seconds slower respectively). None of them qualified for Doha.
So there seems to be a pattern: Somehow all? the top runners were in very bad shape at the trials only 3 weeks before the 1500m heats in Doha?!
The good question: Is Timothy part of the same pattern?
But it does not stop with the 1500m runners. The pattern is even more extreme with the 5000m runners:
Edward Zakayo Pingua did not qualify for Doha since he ran around 1 minute ! slower than his PB best 13:03.19 from DL Rome at the 5000m trials last week (the explanation was illness after African Games where he placed second in the 5000m).
Stanley Waithaka Mburu who ran 13:06.29 in DL Zürich didn´t qualify either. I am not sure if he competed at all at the trials. If he competed he didn´t finish.
Robert Kiprop who beat Edward Zakayo Pingua at the African Games and set PB at the Kenyan Championships in the end of August with 13:21.86 also missed Doha since he only managed to run 13:41.50 at the trials.
Only top 5000m runner to qualify for Doha was Nicholas Kipkorir Kimeli who set PB this year with 12:57.90. In the trials, however, he was no. 3 running 30 seconds slower than PB in 13:27.99.
Kimeli is most likely the only Kenyan 5000m runner to compete in Doha since no. 1 and 2 were sub elite runners who has not been doping tested sufficiently (as already described elsewhere on Letsrun).
It will be interesting to see how much the qualified Kenyan athletes in the 1500m and the 5000m are able to improve their current poor times in the few weeks up to Doha.
