The Ivory Coast international - who was released last summer by Turkish giants Galatasaray - has spent a number of weeks training with the club, and played last week for the U21s side against Leicester, completing a full ninety minutes.
With Adam Matthews leaving to join Bristol City on loan it meant a place in the Sunderland squad became available, so Eboue's signing is as nothing more than a backup option, offering both experience in the dressing room and on the training pitch.
Injury meant Eboue did not feature for the second string in their game against Everton on Monday night, but the player is expected to be back training this week and will be available for selection ahead of the Tyne-Wear derby game on Sunday 20th of March.
Eboue is known for his cheeky nature, and will likely be a welcome face around the dressing room as we head into a high-pressure end to the season.
Who would have known he can speak Korean? Clearly, Emmanuel is a man of many talents.
