The Knights were keen to protect their position with their sponsors after the bad press surrounding the club, following news that forward Houston was charged with three counts of supplying ecstasy and another count of supplying cocaine.
Newcastle CEO Steve Burraston said: “Both meetings held today were constructive and offered an opportunity for our sponsors to discuss a number of concerns.
“Our meeting with NIB was positive and we will now provide further information to assist with their internal discussions and the ongoing relationship between the two organisations.
“The meeting with McDonald’s was also fruitful and they are now considering the information we presented today.
“I’m pleased and thankful both sponsors gave us the opportunity to brief them today.”
