Norwich have completed the signing on Sebastien Bassong on a three-year contract from Tottenham for an undisclosed fee.
Sky Sports revealed earlier on Tuesday that the defender was on his way to Carrow Road.
The Cameroon international announced on his Twitter account that a deal had been done, and Norwich have now confirmed that a transfer has been pushed through.
Canaries boss Chris Hughton has wasted little time dipping into the market for defensive reinforcements after suffering an opening day nightmare at Fulham.
A 5-0 defeat at Craven Cottage has forced his hand, with Bassong drafted in to provide competition for places and Premier League know-how.
The 26-year-old centre-half arrives in Norfolk after four years in England.
He was snapped up by Newcastle in the summer of 2008, before moving on to Spurs after 12 impressive months on Tyneside.
Hughton believes Bassong will prove to be a useful addition to his ranks, as he continues to mould a squad inherited from predecessor Paul Lambert.
"Sebastien is a player that I have known well since my time at Newcastle and I'm delighted to have brought in someone with the Premier League experience he has got," he told the club's official website.
"He will give us power and pace at the back and again add to the competition in the squad."
