Hussey hung up his boots on Wednesday aged 34, after a playing career which spanned 16 years.
The defender only joined Walsall in the summer and made six appearances for the club – scoring once against Wrexham.
Sadler is considering the possibility of signing a replacement, but will only make a move if the right opportunity presents itself.
“I am looking without doubt. But it’s a market which is fraught with people that, at present, haven’t played too many football matches,” he said.
“But I am looking, I’ll keep looking and if the opportunity presents itself then we’ll go for it.
“There is plenty of communication and conversations that have been had, but there is nothing that I have wanted to jump on as of yet.”
