Newcastle are expected to talk with Papiss Cisse in a bid to resolve a potential issue over new sponsor Wonga.
The Senegalese striker is a practicing Muslim and has protested to club officials on religious and ethical grounds about the pay-day loan company's deal which will see their name printed on the team's shirts next season.
Under Sharia law, Muslims must not benefit from either lending money or receiving money from another person - meaning that interest is prohibited. Interest is not paid on Islamic bank accounts or added to mortgages.
Cisse is believed to be on holiday currently and Press Association Sport understands the Magpies will seek to sit down and find a solution to the issue when he returns.
