9:25 p.m. Singaporean swimmer Joseph Schooling has missed out on the 100m butterfly final, meaning he will be unable to defend the title he won at Rio 2016. "The time just didn't reflect everything that we have done this year, sometimes that is just how it is, it is hard to digest," Schooling tells reporters, according to Reuters. "You live to fight another day though, and I sure as hell don't want it to end like this."

1:35 p.m. Indonesia's Rahmat Abdullah has taken many by surprise by winning a bronze medal in the men's 73kg weightlifting. He had competed in a division with lower weight entries, Reuters reports, on the advice of his father and coach who said it would make him "more comfortable and relaxed."

"I am so happy, the plan worked," he is quoted as saying, adding that injuries forced his father to give up his Olympic dream in 2004. "Today I've won the medal for both of us, I dedicate this to him," Abdullah says.
