Professional sports leagues have shut down since the onset of the coronavirus pandemic. Each major organization has been taking different approaches in trying to figure out its next step in terms of returning to play and/or resuming their seasons that were stopped cold by COVID-19.

Here is a breakdown of the latest developments by league:

Major League Baseball Ponders Season In Arizona

Jeff Passan of ESPN reported that Major League Baseball players and owners were formulating a plan to begin the 2020 season with all 30 teams playing in Arizona starting in May without fans in attendance.

The report said players and other team officials would be sequestered between games and the games would be played at 10 different spring training sites in and around the Phoenix area.

MLB on Tuesday issued a statement knocking down the report as being the final, set choice.

“While we have discussed the idea of staging games at one location as one potential option, we have not settled on that option or developed at detailed plan,” MLB said.

But one key U.S. health official seems to see some viability in the plan.

The 2020 MLB season was scheduled to begin on March 26. Players and owners have agreed on how service time will be determined depending on how long a season lasts, or if there is no season at all. Two potential plans had the season starting in either June or July, with multiple double-headers and neutral site playoff and World Series games being potentially played in November.

NFL Moves Forward With ‘Virtual’ Draft, Hopes For 2020 Season

The NFL will proceed with a ‘fully virtual” draft from April 23-25, despite that all team facilities remain closed and nearly 100% of the nation is under official state orders to avoid crowds and practice social distancing. The draft will be televised — naturally — with team officials and players participating from remote locations.

Unbowed by the pandemic, the NFL free-agency period began like any other. Roger Goodell also plans to start the 2020 season on time in September with fans in attendance. The annual release of the NFL schedule has been pushed back until May 9.

NFL executive vice president and lead counsel Jeffrey Pash said on March 31 that "all of our discussion, all of our focus, has been on a normal traditional season, starting on time, playing in front of fans, in our regular stadiums, and going through a full 16-game regular season and full set of playoffs."

Pash added the following caveat: "That's our expectation. Am I certain of that? I'm not certain I'll be here tomorrow. But I'm planning on it, and in the same way, we're planning on having a full season."

The NFL's chief medical official, Dr. Allen Sills, said two days later that any plan to begin play would require widespread testing.

"As long as we're still in a place where when a single individual tests positive for the virus that you have to quarantine every single person who was in contact with them in any shape, form or fashion, then I don't think you can begin to think about reopening a team sport," Sills told NFL.com's Judy Battista. "Because we're going to have positive cases for a very long time."

NBA Plans On Hold Until May

The NBA was the first major professional league to suspend operations after Utah Jazz center Rudy Gobert tested positive for the coronavirus. Gobert and several other players who tested positive have fully recovered.

Commissioner Adam Silver, however, believes there’s no way the NBA can make a decision about when play can resume until May 1 at the earliest.

"Essentially what I've told my folks over the last week is we should just accept that at least for the month of April, we won't be in a position to make any decisions," Silver told TNT's Ernie Johnson. "I don't think that necessarily means that, on May 1, we will be [in that position], but at least I know that just to settle everyone down a little bit.”

Silver added that the NBA was in "listening mode" and has had discussions with "many jurisdictions" about playing at a single site.

The NBA wants to be at the forefront of a return to pro sports, but Silver won’t rush back until the medical officials give the “all-clear.” He raised that point in a phone call with President Donald Trump and several league commissioners this past weekend and again with Johnson Monday.

NHL Weighs Multiple Options

The NHL continues to work on multiple contingency plans to resume its season — which was halted on March 12. And like its professional counterparts, any and all plans remain contingent on restrictions against gathering and traveling being lifted.

The league must first determine whether or not to resume the regular season, which had 189 games remaining, or move directly into a playoff scenario. Training camps and team conditioning are also a universal issue shared among all the major pro entities. The NHL has more than 250 active roster players who are from Europe. Many are now home overseas and cannot return to North America until international travel bans are eased.

The league is looking into playing games through July and August and teams have researched building availabilities for those months. Among the neutral sites under consideration are arenas in Manchester, New Hampshire, and Grand Forks, North Dakota. Maintaining a solid skating surface in warmer climes during the summer may be obstacle for some teams to play at home.

Masters, PGA Championship, U.S. Open Rescheduled

Three of golf’s four major championships have been rescheduled for later in the year, while the British Open has been scuttled until 2021.

The Masters will be played in November.

This sets up perhaps the greatest weekend in the history of televised sports — with the potential of having the Masters, NFL, college football, MLB playoffs, NHL games and NBA games during the same two-day span.

European Soccer Eyes Summer Return

Leagues may be banned from the Champions League if they abandon play for the entire season as UEFA and other European soccer governing bodies plan for a return to play in July and August.

A letter obtained by the The New York Times says the primary focus in resuming play after the current coronavirus stoppage is to complete those seasons that have been halted. And those bodies that do not all they can to finish their seasons will face negative consequences.

“Any decision of abandoning domestic competitions is, at this stage, premature and not justified. Since participation in UEFA club competitions is determined by the sporting result achieved at the end of a full domestic competition, a premature termination would cast doubts about the fulfillment of such condition,” said a portion of the letter issued late Thursday evening and sent to all of UEFA’s 55 national soccer federations and the members of the European Club Association and European Leagues body.

Meanwhile, all MLS operations have been suspended since March 12.
