Others who have left the club this transfer season include Anthony Callaghan, Wade Joyce and Ben Wilson.
Sunderland have confirmed that they have signed Arsenal goalkeeper Vito Mannone.
The 25-year-old Italian has penned a two-year deal on Wearside and has joined up with his new team-mates ahead of this weekend’s trip to Italy.
The news follows Monday’s triple arrival of Cabral, Valentin Roberge and Modibo Diakite.
Mannone initially joined Arsenal as a 17-year-old from Italian side Atalanta in 2005.
He made his debut at the age of 21 and represented the Gunners in the Barclays Premier League and UEFA Champions League, making 15 appearances in all.
The former Italian U21 international also spent time on loan at Barnsley in 2006, making four appearances for the Tykes.
He also had two spells at Hull, playing 11 games in the 2010-11 season plus a further 23 during the following campaign.
