Brazilian defender Cacapa has passed a medical at St James' Park and has now signed a two-year contract with the option of a third season.
And even more good news for the Toon Army, Sam Allardyce has continued to bolster his defence by setting up a deal for Spain Under 21 international Enrique.
Villarreal have confirmed on their website that terms have been agreed for Enrique to move to Tyneside.
The Spanish club have not disclosed the fee, but reports suggest Newcastle have paid 6million euros (£4million) for the youngster.
Enrique joins the defensive acquisition of Czech Republic international David Rozehnal from Paris Saint Germain.
