Holt has signed on loan from League One outfit Wigan Athletic, and he has seen a limited amount of first-team football so far this season.
However, Jackett has been impressed by the target-man’s fitness levels, and he suggests that Holt could be given his first start in the near future.
“I wouldn’t have any qualms starting him if required – he is fully fit and ready," Jackett insisted.
“We have two recognised senior strikers and we needed a third.
“If that third could be someone with size and presence who could win a header then we felt that would complement everyone else.
“Kevin Thelwell has been watching Grant play for Wigan Under-21s after his injury and then the first team and we are pleased to have added him to the squad.”
Holt has previously been a prolific scorer at Championship level, but he is reaching an age now where he is entering the twilight of his career.
The 34-year-old has struggled to break into Wigan’s team down in the third tier, on the back of fitness issues, and he faces a task to break into Wolves’ starting line-up during his time at Molineux.
Wolves have the likes of Adam Le Fondre and Benik Afobe, who are in good form, but Holt offers them a different route to goal.
Both Le Fondre and Afobe prefer the ball on the floor, but Holt allows Jackett’s team to take the aerial route, and he will be hoping to make an impact in the near future.
