Defoe left Rangers this month and has been on the lookout for a new club despite being 39 years old.
The forward is keen to continue to play football and several clubs in League One are interested in getting their hands on the striker.
Sunderland have been heavily linked with a move for their former player and the club are indeed interested.
There is no agreement in place but it has been claimed Sunderland are still in conversations with Defoe in the wake of Lee Johnson’s sacking.
Sunderland and Defoe are in no hurry as his free-agent status keeps them away from the constraints of today’s transfer deadline.
Defoe scored 37 times in 93 appearances in his previous stint at the Stadium of Light with Sunderland.
The Black Cats are third in League One and are pushing to secure automatic promotion back to the Championship.
However, Sunderland are now without a manager after Johnson was sacked following their 6-0 defeat to Bolton on Saturday.
