A very source close to the 31-year-old informed SuperSport.com on Tuesday night that the situation has gone sour following a lack of communication.
The ex-Olympique Marseille has now opted out of joining the Yellow Canaries.
Yobo is now weighing up other options following this decision.
"The deal is off due to issues bordering on lack of communication and commitment. So he will be looking at other possibilities because there are no shortage of interest in him," said a very source to the defender.
