Day eight of Tokyo 2020 is well underway and all eyes are currently on the athletics track. Great Britain's Dina Asher-Smith was knocked out of the women's 100m at the semi-final stage on Saturday, and later revealed - through tears to the BBC - she would be pulling out of the 200m due to a hamstring injury she sustained during the British Olympics trials.
