Tottenham manager Mauricio Pochettino has frequently praised the English-bred
Carter-Vickers, the son of former pro basketball player Howard Carter, extending his contract earlier this summer through the 2020-21 season.
But Carter-Vickers' only appearances for Tottenham came in 2016-17 when he started two games apiece in the League Cup and FA Cup. He dressed 20 times for Spurs in the Premier League and Champions League that season but never got off the bench.
Carter-Vickers played for the USA at the 2015 and 2017 Under-20 World Cups and has started three of the five games for the USA in 2018.
Swansea City dropped its first game of the 2018-19 season on Saturday when it lost at home to Bristol City, 1-0. The Swans started 25-year-old Dutchman Mike van der Hoorn and 20-year-old Welshman Joe Rodon at center back.
They have been looking for help at center back since unloading Federico Fernandez (Newcastle United) and Jordi Amat (Rayo Vallecano) on Deadline Day after selling Alfie Mawson (Fulham) and Kyle Bartley (West Bromwich) earlier in the summer.
