Kikuchi was placed on the COVID-19 injured list Sunday, Ryan Divish of The Seattle Times reports.
Kikuchi recently displayed a symptom of the virus, but he's fully vaccinated and has already produced one negative test result. If he can test negative once more in the coming days, he should be in the clear to participate in his first All-Star Game on Tuesday. The lefty enters the break with a 6-4 record and a 3.48 ERA in 98.1 innings.
