An Oklahoma man was reunited with the doctors who saved his life after going into cardiac arrest.Christopher Fennell was having dinner while visiting his son in Norman, Oklahoma. And as they were leaving a restaurant, Fennell fell to the ground and went into cardiac arrest, which led to a brain seizure. "I was basically dead, and they brought me back," he said. His son is now a junior at the University of Oklahoma and is studying pre-med. He knew exactly what to do to keep his father alive until paramedics arrived. "The quick action of my son to call 911 and then hand the phone to my wife, who was in shock and started CPR was, I mean, I wouldn’t be here without that," Fennell said. Fennell was taken to the hospital, where he stayed in the ICU for 10 days."Out-of-hospital cardiac arrest does not have a very good prognosis overall," Dr. Archana Gautam said. Fennell was later sent to rehab, where he was able to get additional treatment and fully recover. "To see someone physically recover and cognitively recover after a cardiac arrest is rare," said Dr. Lane Tinsley. Fennell said without the quick medical attention from his son, paramedics and the doctors — he wouldn’t have fully recovered. "All of these things God put in place, put breadcrumbs down on the ground to get me here, for the great people here to continue my recovery, put me on the road to recovery and get me back in the position I am in today," he said. "I am a walking miracle, but this is not a story about me. This is a story about how God works in the world today."

The reigning world champion is the favorite.Although reigning Olympic champion Wayde van Niekerk is out, there’s another former winner in the field — Kirani James of Grenada, who won at the 2012 London Games.The sleeper is Anthony Jose Zambrano, who could become the first Colombian man to win a track and field medal at the Olympics.And, there’s a little history to consider: The Americans have never gone three straight Olympics without winning gold in the 400. Team USA failed to win in 2012 and ’16.“I’m just waiting to have a breakthrough and hopefully that breakthrough is on Thursday,” Norman said. Men's BasketballThe U.S. looks to move one win away from its 16th Olympic men’s basketball gold medal when it takes on Australia. The American men have never lost to the Australians in a major competition, going 15-0 in such meetings.Australia has already defeated the U.S. men’s basketball team once this summer, in an exhibition at Las Vegas before the Tokyo Games. The Boomers would clinch their first major international men’s medal — from Olympics or World Cup competition — with a win. They’re 0-10 all time in those competitions when playing to secure a medal.It’s also a matchup that will have U.S. coach Gregg Popovich and Australia point guard Patty Mills opposing one another. Mills was the last remaining member of the 2014 NBA champion Spurs — coached by Popovich — to play in San Antonio. Mills decided earlier this week to leave the Spurs as a free agent and sign with the Brooklyn Nets.

He's been the best player in the tournament and has flirted with triple-doubles in each of his past two games.Now Doncic gets a chance to take his tiny nation to the gold medal game in Saitama. All that stands in Slovenia’s way is France, which knocked off the U.S. to open the Tokyo Games.Doncic is a perfect 17-0 when playing for his national team.

The Matildas reached the medal round for the first time ever at an Olympics and desperately want to leave Kashima with the bronze.The Americans are hoping to salvage a disappointing tournament, which included a scoreless draw against Australia in the final game of the group stage. Australia was also the only team to score on the Swedes, who play Canada for the gold.The United States is the top-ranked team in the world and the defending World Cup champions, but goalkeeper Alyssa Naeher injured her right knee and won’t be available for the final match. Adrianna Franch will get the start in a match.Water Polo The U.S. women's water polo team remains in the hunt for its third consecutive gold medal and faces the Russian Olympic Committee in the semifinals.The Americans are 21-1 this year, with their lone loss coming against Hungary last week.The men’s teams from Britain (1908-1920) and Hungary (2000-2008) are the only countries to win at least three straight water polo titles at the Olympics. SkateboardingIt's the last chance to catch wildly popular skateboarding at the Tokyo Olympics with the men's park final.The format is taken from the style of skateboarding that originated in Venice Beach, California, and features steeper edges of bowls and ramps. That enables higher velocity gains in shorter times — and probably plenty of awesome moves.Heimana Reynolds from Hawaii represents the Americans in the competition.
