West Brom have signed defender George Campbell from Major League Soccer side CF Montreal for an undisclosed fee.
Campbell, 24, can play at right-back or centre-back and has signed a four-year deal at the Hawthorns.
He made his United States debut in January and has played 16 games this season for Montreal - and the deal is subject to international clearance.
"I'm really excited to be here. I honestly can't wait to put on the boots and start training," Campbell told the Albion website.
"When the chance to sign came, I wanted to take it and experience football in Europe.
