The 2022 Paralympic Winter Games will run from March 4-13, and each day, NBCOlympics.com will recap the biggest stories that happened overnight. Here's what you may have missed from the penultimate day of Paralympic competition.

In the final individual race of his storied Paralympic career, Canadian cross-country skiing legend Brian McKeever won gold in the middle-distance visually impaired event. It's the 16th gold medal of his career, tying him with German Alpine skier Gerd Schoenfelder for most all-time by any man in Winter Paralympic history.

With the win, McKeever also completed a clean sweep of all three individual cross-country events contested in the visually impaired class at these Paralympics.

McKeever, who developed an untreatable genetic degenerative eye condition at age 19, began competing at the Paralympics in 2002 and won 10 medals with brother Robin as a guide through the 2010 Games. Many Americans were introduced to the brothers during this year's Super Bowl when Toyota ran a one-minute ad summarizing their emotional story.

In Beijing, McKeever used two different guides: Russell Kennedy for the long-distance and sprint events, then Graham Nishikawa for the middle-distance race. Now 42 years old, McKeever has already announced that he'll be retiring after these Paralympics. With the relay events still to come on Day 9, he could potentially compete again before the Games end.

During the first two cross-country races, McKeever's closest competition came from American Jake Adicoff, the second-place finisher in both events. This time, though, Adicoff faded in the second half of the race and dropped out of podium contention before ultimately finishing sixth.

Sweden's Zebastian Modin took middle-distance silver, while Ukraine's Dmytro Suiarko earned bronze. Earlier this week, Suiarko revealed that his house back in Ukraine had been destroyed by Russian shelling a day before his biathlon middle-distance bronze.

In the other men's middle-distance cross-country races, a pair of Chinese skiers — Mao Zhongwu (sitting) and Wang Chenyang (standing) — won their first gold medals as China continues to lead the overall medal count by a wide margin. Wang edged France's Benjamin Daviet by just 1.3 seconds for the win.

China's Yang Hongqiong completed a sweep of the individual cross-country events, winning the women's middle-distance sitting race by 37 seconds to claim her third gold medal. American star Oksana Masters finished behind Yang once again for her third cross-country silver medal and sixth medal overall at these Paralympics.

Yang, a virtual unknown entering these Games, and Masters have gone 1-2 in all three of the individual cross-country sitting events. At the end of this race, a visibly frustrated Masters embraced boyfriend Aaron Pike, who had just finished 12th in the men's sitting event and was waiting near the finish line.

Masters now has eight cross-country medals in her Paralympic career, making her the most decorated American in the sport at either the Olympic or Paralympic Games. She can add to that total on Day 9 during the relay events.

China ended up taking four of the top five spots in the middle-distance sitting race. American Kendall Gretsch, who earned three biathlon medals, finished sixth.

The other women's middle-distance events were won by Germany's Linn Kazmaier (vision impaired) and Ukraine's Oleksandra Kononova (standing). Kononova's compatriot Iryna Bui joined her on the podium with a bronze-medal finish despite a mishap at the end of the race where she went the wrong way.

For the second day in the row, the three Aigner sisters from Austria shared an Alpine skiing podium in the women's visually impaired class.

Veronika Aigner, with older sister Elisabeth serving as her guide, completed a sweep of the technical events by winning gold in the slalom one day after winning the giant slalom. Their younger sister Barbara Aigner, 16, finished with the silver medal, an upgrade from her giant slalom bronze.

The Aigner siblings have accounted for eight medals so far at these Games — in addition to the three sisters, Barbara's twin brother Johannes Aigner has dominated the men's visually impaired races with four medals (three gold, one silver) in four races and one event still to come tomorrow.

In other women's slalom events, Sweden's Ebba Aarsjoe (standing) and Germany's Anna-Lena Forster (sitting) won their second gold medals of these Paralympic Games.

China defended its Paralympic title in wheelchair curling, defeating Sweden 8-3 in the gold medal game.

The turning point came in the fifth end when, trailing 2-1, China scored four points to take a 5-2 lead. Sweden was only able to respond with one point in the sixth, which gave the hammer back to China with a two-point lead.

That's when the Chinese team was able to put the game out of reach. After Sweden missed a draw attempt with its final stone of the seventh end, China scored three points and Sweden opted to concede the game.

The bronze medal was decided a day earlier when Canada defeated Slovakia by the exact same score.

For the second straight Paralympics, the host nation won bronze in sled hockey as China accomplished the same feat that its opponent, South Korea, managed four years ago. Behind a shutout from goaltender Ji Yanzhao, China blanked South Korea 4-0 to win bronze on home ice.

Shen Yifeng scored two goals and assisted on the other two as China took a lead five minutes into the game. Despite flashing some impressive defense to stay in contention, the Koreans could only manage 11 shots on goal to China's 23.

China, who qualified automatically for the tournament by way of being the host nation, was competing in sled hockey for the first time at the Winter Paralympics.
