(AP) — Major League Soccer will open the 2021 season on April 3 and conclude with the MLS Cup title game on Dec. 11. Teams will be allowed to start preseason camps on Feb. 22.  The announcement of the new season comes amid ongoing uncertainty about the pandemic and whether fans will be able to attend games, especially at the start of the season. There’s also uncertainty surrounding the league’s three Canadian teams. The three teams had to relocate to the United States to finish last season because of travel restrictions back home.
