That message gave the men's US professional golf tour on Saturday since the new corona virus had a major impact on this week's competition in Cromwell, Connecticut. Fitness coaches, instructors and other staff at upcoming competitions will also be covered by the new preventive measure.

Three players - Nick Watney, Cameron Champ and Denny McCarthy - as well as two caddies have tested positive for covid-19 in this week's competition. In addition, six players, including four-time major winner Brooks Koepka, chose to refrain from fear of being infected or possibly spreading the infection themselves.

American Brendon Todd leads Cromwell after three of four rounds, totaling 18 under par, two strokes ahead of compatriot Dustin Johnson. Swedish Henrik Norlander is in shared 39th place, a total of six under par.
