Eight New York Yankees players tested positive for Covid-19 despite being fully vaccinated against the coronavirus.

Shortstop Gleyber Torres tested positive for Covid-19 despite being fully vaccinated, NBC News reported. Torres previously contracted the coronavirus during the offseason.

The news hit the league like a bombshell.

The Yankees canceled a game against the Boston Red Sox on Thursday, after three players – Jonathan Loaisiga, Nestor Cortes Jr. and Wandy Peralta -- tested positive.

Hank Aaron died on January 22, 2021, weeks after receiving the Covid-19 mRNA injection.

Three more Yankees players and one staff -- who were not named -- also tested positive despite being fully vaccinated.

None of the players reported any Covid-related symptoms such as fever, difficulty breathing or coughing.

"Certainly unexpected," said Yankees manager Aaron Boone. "Obviously everyone, Major League Baseball, that's in charge of testing is looking into that. The variants that could be out there if that is the case."

All Major League Baseball teams require their players to be fully vaccinated in order to play.

The Yankees are undergoing additional testing and contact tracing, with the assistance of the baseball commissioner’s office and its medical experts, NBC reports.
