Champ is among six players and two caddies on the PGA Tour who have tested positive. Ricky Elliott, the caddie for Brooks Koepka, tested positive before the Travelers Championship last week in Connecticut, and then had a negative test. Previously, the tour relied on time-based protocols that required those who test positive to self-isolate for at least 10 days. Champ tested positive on June 23 and withdrew from the Travelers Championship. They would be eligible to play next week if they have two negative tests at least 24 hours apart.
