Lambert spent three years at Carrow Road, leading the club from League One to the Premier League in successive campaigns before he walked out to join Villa.
He is unbeaten in meetings with his former employers since leaving, winning two of the three Premier League games played as well as a League Cup clash last season.
However, pressure is beginning to build on the 44-year-old after a poor recent run that has seen Villa slump to 13th - directly above Sunday's opponents - and another defeat would only see that increase.
"Ashley is fine," said Lambert. "I thought he was fantastic on Sunday. To lose him at that time was a blow, but he is fit again."
Midfielder Fer will be monitored before the clash, with Hughton confirming on Friday: "He picked up a hamstring injury but we're still assessing it.
"It's something that's only just happened, so we need a bit of time to assess it.
"Of course, it's a blow for us at this stage of the season but it's one that we'll have to work around as best as we can.
"The good news is that Ryan Bennett is fit and available for selection, but unfortunately Michael Turner and Jonas Gutierrez are still out."
