Jack, who was one of just six recognised defenders currently available for selection, formed part of the Walsall team which has struggled for form over recent weeks, dipping to fifteenth in the League One table and also exiting the FA Cup with something of a bump.
21-year-old Fitzwater spent the first half of the season on-loan at Banks's Stadium, making twenty-five first-team appearances, before returning to the Hawthorns at the start of January in order to take part in the Baggies' FA Cup clash with Wigan Athletic.
Jack, who has also enjoyed loan spells with Chesterfield, Hednesford Town, and Forest Green Rovers since graduating from the Baggies Youth Academy in 2015, was due to return to the Saddlers for the rest of the campaign following the clash with the Latics but he has since remained with his parent club, with manager Darren Moore seeking to add Jack to his first-team options.
Keates, who was speaking in the wake of his side's League One defeat to Scunthorpe United, admitted that he was disappointed by the departure but will be seeking to fill the void over the coming days, whilst ruling out a Walsall return for Fitzwater.
Speaking to the press Dean Keates confirmed Fitzwater's departure, he said; "Jack went back at the weekend, we were told he was going to be playing in the FA Cup and he was meant to be coming back to us.
"That’s changed. He’s not our player. It’s up to West Brom whether they send him back or not. They’ve decided not to send him back. We will be looking elsewhere.
"I’m led to believe they want him to stay so they can have a look at him around their first-team squad. So, for us, we have to look elsewhere. We won’t be hanging about."
