BOSTON (AP) — Red Sox manager Alex Cora said Boston expects to be without multiple unvaccinated players for an upcoming series at Toronto. Starting pitcher Tanner Houck told the Boston Globe on Sunday that he is not vaccinated against COVID-19 and won’t pitch during the four-game series beginning Monday, April 25. He would have been in line to start the second game. To enter Canada, the Canadian government requires a person must have received a second COVID-19 vaccine dose — or one dose of Johnson & Johnson — at least 14 days prior to entry.
