Chase Koepka • Withdrew out of an abundance of caution; neither he nor his caddie, Dan Gambil, have tested positive for COVID-19, but they played a practice round with McDowell (caddie positive) and Brooks Koepka (caddie positive).
The Travelers Championship at TPC River Highlands is the third of five events on the PGA Tour's revamped schedule which is closed to the public in a bid to help stem the spread of the virus.
Mark Cannizzaro of the New York Post tweeted that Brooks' caddie, Ricky Elliott, later posted a negative result.
McDowell says he was at a memorial service on June 15 with Comboy, Elliott and McDowell's trainer, after which they drove up to Hilton Head.
"I feel great physically and I was obviously surprised and disappointed to learn of the test result", said Champ in the PGA's press release.
McDowell tested negative, though he suspects he has the virus and chose to drive home to start his self-isolation.
"We all got tested Monday - myself, [coach] Claude [Harmon] and Ricky".
McDowell said he was feeling a little tired at the end of last week, which he wrote off to having not competed in a tournament for three months and then playing two straight weeks. It's just so hard to control everybody outside the gates.
As part of the PGA Tour's coronavirus plans, anyone who might have come into close contact with a player or caddie who tests positive must submit to a number of coronavirus tests. McDowell said he heard from Lowry, whose test was negative. McDowell said. "You come back and what's changed?" "We continue to find out more about this virus every day, but we know outdoor transmission is much less likely than other activities". Elliott had tested negative two days ago.
And with Cameron Champ also pulling out of £6million field on Tuesday and reports of other infections in the families and entourages of other pros, the PGA Tour's celebrated resumption after the three-month lockdown is inevitably coming under increasing intense pressure.
McDowell said he would take two weeks off and hoped to return in July for the first of two weeks in Ohio.
The PGA Tour is giving more than 1,000 of the same fitness trackers to players, caddies, tour officials and media members.
