Euro 2020 is being postponed for a year due to the coronavirus outbreak, UEFA has confirmed.
European football's governing body said its other tournaments and matches - involving both domestic and international teams in the men's and women's game - were also on hold "until further notice".
That means the Champions League and Europa League are paused for the time being.
UEFA said a "working group" was being set up to "examine possibilities" for the two tournaments, which see Europe's best clubs face each other and are worth tens of millions in revenue.
Euro 2020 was due to be played across Europe in 12 different countries, including England, and is now pencilled in for 11 June - 11 July 2021. A UEFA statement said suspending the tournament would help domestic leagues to hopefully finish their seasons.
"The health of all those involved in the game is the priority, as well as to avoid placing any unnecessary pressure on national public services involved in staging matches," it said.
"The move will help all domestic competitions, currently on hold due to the COVID-19 emergency, to be completed."
