It said they would be part of the Dortmund squad travelling to the club's winter training camp in Dubai and would take part in first team training from now on. They could also be called up to the squad when needed.
The duo are set to help fill the gap left by midfielder Jonas Hofmann, who joined Borussia Monchengladbach for a reported €8 million earlier this month.

Attacking midfielder Pulisic has been one of the outstanding players for Borussia Dortmund's youth academy since joining in January 2015.
He has been a key player for their under-19 side, who currently lead the regional first division, scoring four goals and setting up a further three this season.
The youngster played for the first team in a friendly at second tier club FC St. Pauli in September, and in February former Dortmund coach Jurgen Klopp said: "He's a great footballer. He can pass the ball around really well."
