It was reported on Friday that the 20-year-old was close to agreeing a temporary deal with the Scottish Premiership side.
"Aberdeen have come in and they want to take him on loan until Christmas," Jackett is quoted as saying by Sky Sports News.
"They came in very strongly and very enthusiastically for Zeli. So it's a really good opportunity I think and it does seem like they're very keen on him which is good from a player's point of view.
"It's an interesting one for us and one that we're currently discussing."
Ismail signed his first professional contract with Wolves in 2012 after graduating from the club's youth academy.
