Boston Red Sox Pitcher Tanner Houck Can’t Pitch In Toronto — Guess Why?

The Boston Red Sox will be without at least one player in their series against the Toronto Blue Jays next week due to vaccine status.
Tanner Houck won't be with the Red Sox from Monday to Thursday next week. That's because people must be vaccinated against coronavirus to enter Canada and Houck is not vaccinated, as Sporting News points out. The Toronto Blue Jays are the only Major League Baseball team in Canada.
