We're in the home stretch of the Sochi Winter Olympics, with the final week of competition under way.
NBC's Bob Costas plans to return to the broadcast booth Monday after being sidelined with an eye infection for a few days.
More importantly, Monday will determine whether we'll get to see a repeat of one of the most intense rivalries in sports. And it will offer us a taste of the chaotic world of snowboard cross.
Here are five events to watch at the Sochi Winter Olympics on Monday:
1. Ice Dancing
Americans Meryl Davis, 27, and Charlie White, 26, are favorites to win gold in ice dancing. They were the world champions in 2011 and 2013 -- and could become the first Americans ever to become Olympic champions in ice dance.
On Sunday, they not only won the short dance part of the competition; they scored a world-record 78.89 points.
The free dance takes place Monday.
Who else to watch:
Davis and White's chief rivals - Canadians Tessa Virtue and Scott Moir, who came in second in the short dance Sunday. But they are the defending Olympic champions, having won gold at the Vancouver games four years ago.
2. Women's Ice Hockey
Though it doesn't get the attention it should, the U.S vs. Canada women's ice hockey is one of the most intense rivalries in sports.
Since the sport was included in the Olympics in 1988, no other country but these two have taken home the gold.
The Canadians won gold in 2002, 2006 and 2010. The U.S. won in 1998.
The teams want to face each other again in the gold medal game -- but first, they have to win their semifinals Monday.
The U.S. faces Sweden at 7:30 a.m. ET and Canada plays Switzerland at noon.
Who to watch: Julie Chu, one of the U.S.'s top players, injured her hand in practice Saturday but is expected to play.
3. Men's two-man bobsled
One of the feel-good stories of Sochi was the return of the Jamaican bobsled team after a 12-year absence.
The sunny, snowless Caribbean island inspired the Disney movie "Cool Runnings" after fielding a four-man team to the Calgary games in 1988.
But Jamaica never got any traction at Sochi. After the first round of heats Sunday, Winston Watts and Marvin Dixon of Jamaica are 30th among 30 teams. Last place.
The second day of heats is Monday. Russia holds a big lead, followed by Switzerland, the U.S. and Canada.
Who to watch:
The Russians. Could this be their year? They won silver in 2006 and bronze in 2010. Taking the gold before a home crowd would be especially sweet for them.
