Michael Sam left Canada due to "personal reasons."

Sam's CFL team, the Montreal Alouettes, explained the situation in a statement.

"Friday morning, Michael asked the team for special permission to leave training camp and return home for personal reasons. Out of respect for Michael Sam, the nature of this decision will remain confidential," the statement said. "The Montreal Alouettes fully respect Michael Sam's decision and we rally around him to offer all the support needed."

The Alouettes also added that Sam would be welcomed back if he chooses to return.
