Cisse will make his first appearance of pre-season against Scottish side St Mirren on Tuesday night, having been at loggerheads with Newcastle over the deal with payday loan company Wonga, which the striker said conflicted with his Muslim beliefs.
The Senegalese star, who earns £40,000 a week, missed the club's training camp in Portugal over the row, but insists he is now ready to concentrate on his game and was spotted training in kit carrying the Wonga branding.

Backing down: Cisse talked to Islamic teachers before deciding to wear the club's new shirt
'I have had some useful discussions with my club, my family and Islamic teachers in the last few weeks. After a huge amount of thought and reflection I have made the decision to follow my teammates and wear the kit,' he said.
'Now I think it is important for the team and the fans that we concentrate 100 per cent on football.
'Although I did not go to Portugal on the training camp, I was back here working hard on my fitness and preparing for the start of the new season.
'Since then it has been great to be training with my team-mates again. I feel great and ready to go, and cannot wait to be out there against St Mirren on Tuesday and to play my part for the team.'
