Looks like they are going with what they have to replace Vertongen and CCV will get the shot if needed.

Not so, says Spurs' manager Mauricio Pochettino. Poche made statements to the media suggesting that not only will Spurs not panic-buy a defender while Vertonghen recovers, but that they will promote teenage English-American defender Cameron Carter-Vickers should the need arise.
"We have a lot of players in defensive positions that can play. We have another youngster from the academy, Cameron Carter-Vickers.
"He’s young but he has enough quality and he’s been training with us from the beginning of the season and playing with the Under-21s.
"I think it’s a good opportunity [for him] to stay with us now more consistently. I don’t expect to [sign a player to] cover Jan Vertonghen, I think we have enough players to cover his injury."
