Tottenham were hoping to complete the signing of Ryan Nelsen after the transfer deadline following the defender's release by Blackburn.
Spurs were awaiting international clearance after agreeing terms with the 34-year-old New Zealand captain, according to his agent.
Lyle Yorks, Nelsen's Washington-based representative from James Grant Sports, told the Washington Post: "We settled with Blackburn and have reached agreement with Spurs. We're just awaiting clearance. It's for six months, with a one-year option. It all unfolded quickly."
