Lipsiuc has played four times for the Potters in the Premier League 2 since arriving on loan at Walsall until the end of the season on transfer deadline day in February.
The midfielder, who is currently on international duty with Ireland under-21s, is yet to feature in a match day squad for the Saddlers.
But Sadler feels the arrangement with his parent club Stoke will ensure that Lipsiuc is ready to play when called upon.
