"The only one who is missing this weekend is Sam (Tuitupou) who I have given permission to go back to New Zealand for a family matter," said Ruddock.
"He will return on Monday and will be available for the Saracens game next week.
"Sam hasn't signed a new deal, but it has been agreed and we're hoping that when he comes back that will happen. I am optimistic that will be the case.
"We've been working behind the scenes for a number of months really with Sam. He is enjoying playing for Warriors, is very happy here and hopefully that will continue over the longer term."
