90 seconds to go. Lots of tangling, but no more points. Muhammad on course for a place in the semis.

We have a horse draw for the show jumping. Who gets what? The beautiful ballerina horse or a bucking bronco?
One animal just kicked off and almost took out several others. I'd want that one. Seems game.
After the jumping there's a break and then on to a 3,200m run which includes some shooting.
Samantha Murray - silver at London 2012 - has a lot of ground to make up.
Men's -80kg
No score at all in that second round, Muhammad leads 4-1. Joe Joyce is due in the ring next...
Men's -80kg
Muhammad bobs on the spot, flexing his knees. They get into an almighty tangle, but no points are scored.
Men's -80kg
Second round already under way, Lopez looking to dance to make a mark on that Muhammad lead. Nothing doing.
Women's BMX
London 2012 gold medallist. Reigning world champion. And now Olympic gold all over again.
Colombia's Marion Pajon has looked unstoppable over the BMX bumps and she's just absolutely delivered to retain her title and send a load of Colombians in the crowd bonkers.
USA's Alise Post took silver and Venezuela's Stefany Hernandez bronze.
Men's -80kg
Better from Muhammad. A kick to the head and another to the body. He's 4-1 up at the end of the first round.

Where once there were rugby sevens players, now there are jumps for modern pentathlon.
Where once rugby sevens players warmed up, now there are horses for the show jumping element.
Remember, the athletes don't know their horse. They have 20 minutes to get acquainted. That discipline is next.
Great Britain's Samantha Murray is 14th after swimming and fencing. Kate French is 15th.
Men's -80kg
A kick from Lopez lands, Muhammad goes a point behind.
Men's -80kg
Remember, points are scored by landing kicks or punches. Muhammad, in red, is exploring with a leading left foot.
Men's -80kg
Lutalo Muhammad is ready to go, so taekwondo will have our attention first. America's Steven Lopez the opponent. A place in the semi-finals at stake. Three two-minute rounds.
