The Charles Schwab Challenge at Colonial Country Club could tee off in June, not May. Golf Digest reports the PGA Tour will release a revised schedule this week with the Fort Worth tournament to restart the season on June 11th with likely no fans. It was scheduled for Memorial Day weekend. The June dates correspond with the RBC Canadian Open, but Toronto has canceled all major events through June 30th. The refurbished schedule would still be under the guidelines of government and health officials.
