The list of Paris Olympians pulling out of competition because of water quality concerns with the Seine River added Sweden's Victor Johansson Thursday.

Johansson pulled out of the Olympic men's 10-kilometer event Friday after getting sick from swimming in the river during Olympic competition, he told Swedish newspaper Dagens Nyheter. 

Johansson said swimming in the river didn't feel good from the start, and he knows for sure others have become ill.

Since the Paris Olympics began, bacteria levels in the river have fluctuated and affected certain events. Test swims ahead of the triathlon events had to be canceled due to bacteria levels, and the men's triathlon was delayed by a day for the same reason.

Johansson is not the first athlete to pull out of competition in Paris over concerns about the river. Belgium withdrew its entire team from the triathlon mixed relay Monday after Claire Michel of Belgium withdrew from the contest after feeling sick. However, Michel later said blood tests showed it was a virus that made her sick and not E. coli bacteria, which is said to be the biggest risk of swimming in the Seine.

Belgium's Jolien Vermeylen told TV channel VTM she felt debris in the water during her 1500-meter swim in the French river at the beginning of the women’s triathlon Wednesday.

About $1.5 billion was invested to upgrade the city's sewer systems for the Olympics, promising the world the historically dirty, bacteria-filled river would be clean for residents to swim in.

Under world triathlon guidelines, E. coli levels up to 1,000 colony-forming units per 100 milliliters can be considered "good" and allow competition to move forward. There have been daily water tests of the Seine during the Olympics.

Johansson, 25, is a first-time Olympian in Paris. In 2019, he won gold in the men's 1500-meter freestyle event representing Sweden at the 2019 Summer Universiade in Naples, Italy.

Noah Lyles' "dream goal" for the Paris Olympics was to break the world record in the 200M, but plans don't always work out how you hope.

Four days after winning the United States' first gold medal in the men's 100m since 2004, Lyles took the track to accomplish a feat last done by Carl Lewis in 1984: winning both the 100m and 200m representing the Stars and Stripes.

Lyles entered the Paris track as the overwhelming favorite in, by far, his best event as a three-time world champion (2019, 2022, 2023). However, he was never able to recover from a rough start and had to settle for bronze.

Lyles crossed the line at 19.70, nearly a quarter-second off gold-medal winner Letsile Tebogo of Botswana, and 0.39 seconds off his own personal best.

After the race, Lyles needed to be tended to by medical staff. He was seen wearing a mask on Wednesday and before the race on Thursday. NBC then announced that Lyles had tested positive for COVID-19 two days earlier, finding out from his "distraught" mother. USA Track and Field confirmed the positive case to the BBC. He is also asthmatic.

Lyles' reaction time of 0.173 was the slowest of the eight runners in the race. He was tied for the slowest reaction time in the men's 100m, as well, but he still managed to pull off a personal best of 9.79, winning by five-thousandths of a second. Of course, that was before he was sick.

Lyles also settled for bronze in Tokyo. American Kenny Bednarek earned his second-straight silver medal in the event.

Nonetheless, Lyles doubled his total Olympic medal count with the race - he now has three in total.

Depending on his health, the 27-year-old now figures to turn his attention toward the men's 4x100 meter relay. Lyles did not run in the preliminaries on Thursday morning, likely to conserve any energy for the 200m.

With the new COVID-19 diagnoses, it remains to be seen whether he will run in the final. He was a part of the world championship team last year in Budapest.
