Most Blue Jays players arrived in Toronto from Florida earlier this week to continue spring training.
They have been living at the hotel connected to the Rogers Centre.
The Red Sox and Blue Jays will play two exhibition games at Fenway Park on July 21 and 22.
The Jays will then head down to Tampa Bay for their season opener.
