Shane Bieber didn't report to training camp with the rest of the Cleveland Indians' pitchers.
The reigning American League Cy Young winner recently tested positive for COVID-19 and has not yet reported to the club's facility in Goodyear, Arizona.
Chris Antonetti said Bieber had contracted the virus and would be delayed in joining his teammates.
"He has very, very mild symptoms," Antonetti said. "In fact, they were barely noticeable. He's working through the protocols to return. We expect him to get back to the complex at some point within the next few days."
Antonetti would not disclose when Bieber tested positive. Per Major League Baseball's protocols, Bieber has to isolate for at least 10 days from the time he tested positive.
