Tottenham have recalled United States international Cameron Carter-Vickers from a loan spell at Sheffield United, while Spurs winger Marcus Edwards has joined Norwich on loan for the rest of the season.
Carter-Vickers moved to the second-tier club on a season-long loan in August, but Spurs boss Mauricio Pochettino wants him back him with his parent club.
He played 17 times for the Blades in the Championship, scoring on his full debut against Bolton, and he made his full U.S. debut in a November friendly.
Carter-Vickers started four Spurs matches in the domestic cups last season and, ahead of his debut against Gillingham, Spurs manager Mauricio Pochettino said he could become "one of the best centre-backs in the country."
Last month, Pochettino hinted at recalling the 20-year-old, saying the decision would be "more about his development than if we need or don't need some more centre-backs in the squad."
Pochettino added: "The decision will be together with John [McDermott, head of coaching and development], Dean [Rastrick, academy manager] and Steve [Hitchen, chief scout] and of course the club.
"We are trying to provide the player [with] the solution, but not because maybe we need to cover the position."
Edwards, 19, also made his senior debut as a substitute in the 5-0 EFL Cup third-round win over Gillingham in Sept. 2016 and was a member of England's European Under-19 Championship squad in July last year.
Pochettino has compared the prodigal winger to Barcelona's Lionel Messi.
