The former Chelsea left-back is glad to have the chance to play games again, particularly for the side who have experienced a revival under new manager Martin O'Neill
The Black Cats have moved up the table since Martin O’Neill replaced Steve Bruce at the helm in December, and the left-back is excited to be part of their revival.
“I'm delighted to make the move. I have met the manager and the lads and everyone seems great,” Bridge told Sunderland’s official website.
“I'm just excited to start playing football and playing a few games. The club is on the up - the manager has come in and done very well.
“Just coming in and speaking to him, everything has been positive. I have trained with the lads and they are a great bunch who are feeling really positive.
“Hopefully I can help the club progress even more.”
Bridge, who has 36 England caps to date, had only featured once in the 2011-12 campaign in a City shirt, a League Cup fixture in September, before making the switch to Wearside on a temporary basis.
His first appearance for the 10th-placed side could be on Wednesday when they host Norwich City, who are two points above them in the Premier League.
