The United States retook the overall medal count on Wednesday thanks to a good day in track & field, but the USA will need a strong Thursday to maintain their medal count lead.
The United States is assured of at least a silver medal in women's soccer, but they will go for the gold against Japan. The matchup is a rematch of the 2011 women's World Cup final that Japan won on penalty kicks.
The United States will look for another strong day on the track Thursday, headlined by Ashton Eaton's quest for gold in the men's decathlon. Eaton holds a 220-point lead over fellow American Trey Hardee through the first five events. The two will battle for the top spot over the remaining five events Thursday.
Team USA will also attempt to add medals in the men's triple jump, men's 800m and men's 200m on Thursday.
Here's a more complete look at the medal count:
United States: 81 (34 gold, 22 silver, 25 bronze)
China: 77 (36, 22, 19)
Russia: 52 (11, 19, 22)
Great Britain: 48 (22, 13, 13)
Germany: 32 (7, 15, 10)
