FC Basel have confirmed midfielder Cabral is moving to Sunderland.
The Black Cats are understood to have agreed a deal to sign the player when his contract with Basel runs out at the end of this month.
Ahead of FC Basel's final league game of the season on Saturday, a message on FC Basel's official Twitter account said: "The game is about to start at the Joggeli [the nickname the club uses for their ground, St Jakob-Park], but first a few honours. It starts with Cabral, who is moving to Sunderland!"
