Swansea City have signed Tottenham's United States defender Cameron Carter-Vickers on loan for the rest of the season.
The 20-year-old centre-back had been linked with several Championship clubs following loan spells at Sheffield United and Ipswich Town last season.
Swansea sold centre-backs Alfie Mawson, Federico Fernandez, Kyle Bartley and Jordi Amat this summer.
The loan window for EFL clubs closes on 31 August.
Carter-Vickers, who was won four caps, signed a new Tottenham deal until 2021 in May.
He watched Swansea's unbeaten start to the season end in a 1-0 defeat by Bristol City at Liberty Stadium.
"It's an area of the pitch that we need help in and competition because we've got Mike [van der Hoorn] and Joe [Rodon]," said Swansea manager Graham Potter.
"He [Carter-Vickers] has had experience in the Championship last year and the year before as well.
"He's been at Tottenham, he's got some really good attributes that we can use and we're looking forward to working with him and helping him improve. Hopefully he can help us."
Carter-Vickers will not feature in Tuesday's EFL Cup match at home to Crystal Palace because of a minor upper leg problem.
Swansea may also want to rest Oli McBurnie, even though the Scotland international is currently the only fit recognised striker at the club.
McBurnie was replaced by midfielder Leroy Fer against Bristol City, with Potter revealing the 22-year-old striker has been playing for a "couple of weeks" with a cracked bone in his toe - an injury he says will not mean an enforced lay-off.
"Oli's given such a lot over the last few weeks. He's been fantastic," said Potter.
"He's had a little crack in his toe so he's playing with a bit of pain. I thought his energy levels were a bit low today but he's OK."
