New York Red Bulls defender Tim Ream will train with West Brom and Bolton over the next fortnight.
His agent Patrick McCabe said, though, a potential January move for 24-year-old Ream would have to be right for the player.
McCabe told the Wolverhampton Express and Star: "Both clubs (Albion and Bolton) have admired Tim for some time and it affords both parties a chance to see each other up close. Roy Hodgson and Owen Coyle are top managers and, above all, this will be a good opportunity for Tim's professional development."
He added: "But Red Bull has maintained that Tim is an important piece of the club for next season. Tim certainly is interested in moving to Europe but, at the right time and under the right conditions.
"But he still needs to play regularly and Red Bull currently provides that. As he moves toward the end of his contract, I believe that there will be some interesting options for him in Europe in the future."
