The escalation of the coronavirus outbreak is forcing sports leagues and teams throughout the world to reconsider their plans for upcoming games and matches.
With government officials recommending -- and in some cases requiring -- that residents avoid gatherings with large crowds, many events have been canceled, postponed or will be closed to the public.
As the global death toll topped 4,300 and the number of confirmed cases exceeded 121,000 on Wednesday, the World Health Organization declared the coronavirus outbreak a pandemic and issued a prophetic warning that "it's going to get worse."
Here are the latest developments in the sports world:
 
NBA suspends season
Shortly after determining that Utah Jazz forward Rudy Gobert tested positive for the COVID-19 virus, the National Basketball Association took the unprecedented step of suspending the 2019-20 season indefinitely.
Wednesday's game between the Jazz and Thunder in Oklahoma City was abruptly postponed after the players participated in pregame warmups. The two teams were quarantined after receiving word of Gobert's positive test.
Earlier in the week, Gobert had joked with reporters about the coronavirus and touched reporters' recorders as he left a session with the media.
 
NCAA tournament is on for now, but closed to fans
The NCAA announced Wednesday the men's and women's basketball tournaments will be held as scheduled at all venues next week, but without fans present.
"While I understand how disappointing this is for all fans of our sports, my decision is based on the current understanding of how COVID-19 is progressing in the United States," NCAA president Mark Emmert said. "This decision is in the best interest of public health, including that of coaches, administrators, fans and, most importantly, our student-athletes.”
The 67-game men's tournament will be played in empty arenas at 14 sites throughout the country.
 
Four conferences reverse course
Even though some of their basketball tournaments had already begun, the ACC, Big 10, Big 12 and Pac-12 all announced the remaining games in Greensboro, Indianapolis, Kansas City and Anaheim will be closed to the public, beginning on Thursday.
The ACC had already completed its first two days of competition, but changed its mind "(a)fter consultation with the league’s presidents and athletic directors."
The Big 10 said attendance will be limited to student-athletes, coaches, event staff, credentialed media, TV network partners and immediate family members of the participating teams.
Big 12 commissioner Bob Bowlsby said 125 tickets will be provided to teams for games. Arenas will be cleared between games.
The Pac-12 made its decision to restrict people allowed in the arena to essential staff, TV partners, credentialed media and limited family and friends.
And later Thursday, the SEC followed suit and said it's league tournament would continue, but only with essential personnel in the building.
 
Ohio bans fans indoors
Ohio governor Mike DeWine is set to issue an executive order that bans spectators from attending indoor sporting events, including the NCAA Tournament's First Four in Dayton, starting March 17, as well as the first and second rounds in Cleveland, beginning March 20.
The ban would have impacted the Cleveland Cavaliers before the NBA stepped in and suspended its season but could have an effect on the NHL's Columbus Blue Jackets. However, it won't affect MLB's Cleveland Indians, who play outdoors and are scheduled to begin their season at home on March 26.
 
Mariners to open on the road
MLB's Seattle Mariners, also scheduled to open their season at home March 26, are looking for alternate sites for their first two series -- as a result of the COVID-19 outbreak that has hit their state especially hard.
Washington governor Jay Inslee on Wednesday announced restrictions through the end of the month on large gatherings of more than 250 people in the three counties most impacted by the virus. That includes King County, where the Mariners' T-Mobile Park is located.
 
No crowds allowed in Bay Area
The city of San Francisco has initiated a ban on events of more than 1,000 people, which directly impacted the NBA's Golden State Warriors and their G-League affiliate before the NBA suspended the season.
The Warriors were to have played host to the Brooklyn Nets on Thursday with no fans in attendance, while the the G-League Santa Cruz Warriors would have done the same for at least their next four home games.
The San Jose Sharks of the NHL will also close their next three home games to the public.
Meanwhile, the MLB exhibition game between the Oakland A's and host San Francisco Giants on March 24 will not be played at Oracle Park.
Across the bay in Oakland, the city has ordered gatherings of over 1,000 people to be cancelled or postponed -- which would include the A's first two series of the regular season.
 
Ivy League cancels spring sports
A day after canceling its men's and women's basketball tournaments, the Ivy League took its coronavirus response a step further on Wednesday by canceling the entire spring sports season for each of the conference's schools.
The decision impacts all games and practices -- even in some spring sports, such as men's and women's lacrosse, which had already begun their regular seasons.
 
World Cup skiing finale canceled
The final event of the women's Alpine skiing World Cup season has been called off due to coronavirus concerns. The International Ski Federation, FIS, announced the cancellation less than 24 hours before the first race in Are, Sweden -- Thursday’s parallel giant slalom.
Next week’s World Cup finals for both women and men in Cortina d’Ampezzo had already been canceled because of the virus outbreak in northern Italy.
 
Overwatch halted through April
Even eSports are being impacted by the coronavirus outbreak. The Overwatch League announced Wednesday it's canceling all live events in March and April, although competitions will still take place and matches will be streamed online.
The league says it's "working with teams to see that all matches are played when it's safe and logistically feasible."
The fledgling Call of Duty League's tournament-style schedule may also be impacted.
 
No pro soccer matches in Spain for two weeks
After saying matches over the next two weeks would take place behind closed doors, the league announced Thursday it was postponing the schedule at least two weeks after a member of Real Madrid's basketball team tested positive for coronavirus.
As a result, the Real Madrid soccer team placed all of its players under quarantine and canceled training for a fortnight.
