The forward has barely featured for the Championship side this past season.
The 24-year-old missed almost all of this past season after suffering a cruciate knee ligament injury against Charlton back in August, but the Mail reports that he is now back training and could be back in action for the start of pre-season.
Nevertheless, Jackett has chosen to dampen hopes that the striker will take little time to return to his best, and suggested that there should not be too much of burden put on his shoulders.
"It will be great to get Dicko back, although I don't want to put too much pressure on him from the start," he told the Mail.
"Similarly, he's talking very positively and he wants to be ready."
Despite Jackett's warning, it would be understandable if the supporters were hopeful regarding Dicko's return to the team.
While he was unable to make a major impact this past season, his 15 goals in all competitions the previous year nearly helped the club into the play-off places as they only missed out on goal difference.
And with a lack of goals proving to be the narrative of their most recent campaign following Dicko's injury and Benik Afobe's departure, the Mali international's return would undoubtedly strengthen their chances of getting back into the promotion picture.
