Defoe passes Sunderland medicalpublished at 16:15 Greenwich Mean Time 15 January 2015
BBC Sport understands that Jermain Defoe has passed his medical and agreed personal terms with Sunderland.
However, the deal is thought to involve a straight player swap, with Jozy Altidore going to Toronto and no transfer fees being exchanged.
Sunderland are now awaiting news from Toronto and are hopeful that the deal will go through in time for Defoe to be registered for the match against his former club, Tottenham, on Saturday.
