Players disappearing!!

[Jeeves]

If the player's team was/is about to attend a match or was in the middle of one, the player won't be able to come to your team until the match is over. See if he's still missing after a while and if so, write to our support team about his absence.

Players bought on auction come from Team Nordeus, don't they?
How can they be just about to start a match?
