The Open Championship -- the oldest golf tournament in the world -- has been officially canceled ... all because of coronavirus.
The Royal and Ancient Golf Club of St Andrews made the announcement Monday ... with the chief executive saying they tried everything to make the 149th Open Championship happen in July.
"I can assure everyone that we explored every option for playing The Open this year but it is not going to be possible," Martin Slumbers said of the cancellation.
Now, the plan is to move everything back a year ... with the 149th Open scheduled to take place at Royal St.
