Fitzwater, who has made sixteen first-team appearances so far this season, decided to return to the Saddlers over the summer despite being given the opportunity to stay with his parent club and try and work his way out of the development side.
The defender, who also enjoyed a sixteen-game loan spell at the Banks's last season, is keen to continue his development with regular football in the hope of giving the gaffer little option but to give him a chance in the side, and 41-year-old Burton thinks Jack's development is going well.
Speaking via the Express & Star, Deon said; "His development is going as well as could be expected. He’s played every single minute of every game so far. That definitely shows he’s maturing and a vital part of Walsall’s team.
"He’s developing and stepping up so the next step I’d say, is back here with the first team. That’s the end goal. He is close. This loan will be the one where he’s judged. He’s ticking all the boxes.
"He’s doing something right and hopefully the management and first-team staff see he has what it takes for the next step-up which is obviously a bit more difficult."
Burton, a former Jamaica international, confirmed that Jack, and all of the other West Brom players currently enjoying loan spells, will return to the Baggies in January to be assessed with some likely to return to their temporary clubs whilst others may stay at the Hawthorns or even join a different club entirely.
Burton continued; "If it’s not right for us and the player then we’ll definitely look at it, check where we’re at and how best to move forward for each individual.
"With some it might be part and parcel of development, others we might say ‘no’, get them back in the building for a couple of weeks and send them somewhere else.
"At the end of the day it’s down to the parent club if they want the player back. No decision has been made and nothing will be made until a later date. At the moment we’re happy with all our players and where they are."
