2020 Major League Lacrosse season

The 2020 Major League Lacrosse season was the 20th season of Major League Lacrosse. Each of the six teams were slated to play a ten-game regular season starting on May 30, until the COVID-19 pandemic suspended the season. On July 2, the league announced teams would play a five-game regular season over the course of a quarantined week in Annapolis, Maryland at Navy-Marine Corps Memorial Stadium, the home of the Chesapeake Bayhawks. The regular season was scheduled to begin play on Saturday, July 18 with a four-team postseason the next weekend on July 25–26.

The Bayhawks entered the season as defending champions. They claimed their sixth title after defeating the Denver Outlaws, 10–9 in the 2019 Steinfeld Cup Game at Dick's Sporting Goods Park in Denver.

For the second consecutive offseason, the landscape of the league changed dramatically. On January 14, the league announced the switch from a franchise model to a single-entity structure, meaning they will operate all six teams in 2020. On February 10, the league ceased operations of the Dallas Rattlers and moved the players and team staff to a new franchise, the Connecticut Hammerheads. The next week, the league ceased operations of the Atlanta Blaze and relocated the roster and coaches to relaunch the Philadelphia Barrage.

On the last evening of the shortened regular season, an unnamed player reported to team officials exhibiting symptoms of COVID-19. All league players were tested the next day. In result, the semifinal games on July 25 were canceled and the Bayhawks and Hammerheads, who were scheduled to play in the semifinal round, backed out of the postseason. The league announced the canceled semifinal game between the top seed Denver Outlaws and fourth seed and Boston Cannons would be pushed to July 26 and act as the championship game. Boston defeated Denver 13–10 to claim their second championship in franchise history.

On December 16, 2020, the league announced that it had merged with its competitor, Premier Lacrosse League.

Coaching changes

 * On January 16, 2020, shortly after the league announced it would be transitioning from a franchise model to a single-entity structure, Dave Cottle stepped down as head coach of the Bayhawks. He was replaced by assistant Tom Mariano, who also spent time as head coach for the Florida Launch.
 * On February 17, 2020, Spencer Ford was named as head coach for the Philadelphia Barrage, after most of the disbanded Atlanta Blaze players and team staff were transferred to the Barrage reincarnation. Ford most recently served as general manager for the Blaze, and Liam Banks, who coached the Blaze to their first playoff berth in franchise history in 2019, elected not to make the move to Philly.

Broadcast
Shortly after the league informed fans of its plans for a shortened season, it was announced that all 18 games would be broadcast on the ESPN family of networks. Two regular season games were aired on ESPN2 on July 19 while the championship game on July 26 aired on ESPN's flagship station. All other games would stream on ESPN+ and would be available to over 100 countries via ESPN Player. Canadian viewers were able to watch every game via TSN.

Collegiate Draft

However the next day, Ierlan announced he would be returning to Yale in 2021 after the pandemic-shortened 2020 NCAA season. Second overall pick, Michael Kraus, an attack from Virginia, signed a two-year contract with the Connecticut Hammerheads on May 14.

Playoffs
After positive COVID-19 test results among players, the Connecticut Hammerheads (second seed) and Chesapeake Bayhawks (third seed) backed out of the postseason.
