After Day started its tour, the PGA Tour said in a statement that it had tested negative for COVID-19.
If his test came back positive, according to the procedures of the PGA Tour, he would have been removed from the golf course at mid-course and put in isolation.
Day got a 69 on Saturday and is 13 strokes behind leader Brendon Todd who enters the final.
The PGA Tour had seven withdrawals this week related to the coronavirus. Players Cameron Champ and Denny McCarthy have both tested positive. Bud Cauley, who played with McCarthy in the first round on Thursday, chose to withdraw before the second round on Friday as a precaution, despite a negative test.
The cadets of Brooks Koepka and Graeme McDowell were both tested positive, resulting in the withdrawal of each player. Brooks’s brother Chase Koepka, who secured a spot on the field through Monday’s qualification, also withdrew from the event for precautionary reasons as he was close to his brother’s younger brother, Ricky Elliott. Webb Simpson also withdrew before the start of the event after discovering that a family member had tested positive for the virus.
The tour said in its statement that all of the follow-up tests of potential contact with McCarthy were negative.
On Wednesday, PGA Tour Commissioner Jay Monahan announced stricter protocols for the safety of everyone involved and to allow golf to continue without interruption. He announced additional tests and expanded the scope of those to be tested, including player instructors. He promised “serious repercussions” to anyone who did not follow the protocols.
“It is pretty clear that this virus is not going anywhere,” said Monahan.
“But everyone knows and should know that our future, our ability to support this business and have an impact on the communities we play in and to create so many jobs depends on our ability to follow these protocols. So when we have cases where someone hasn’t been treated. And as I said, the consequences will be significant. “
