Mason was brought to Wolves from Cardiff City as their big money signing in the January transfer window, but he has dropped out of favour more recently.
The 24-year-old has regularly been used from the substitutes’ bench of late, and he was only introduced in the 85th minute of Wolves’ 0-0 draw against Birmingham City earlier today.
Wolves fans have criticised Jackett for not showing more faith in Mason but the 54-year-old insists that the striker will have a big part to play.
"It's been difficult for us to get to two up front, which ultimately I think Joe does need,” Jackett said.
"We've lost a lot of goals in our side, even in recent weeks with James Henry and Dave Edwards, who are capable of scoring.
"We need to find a new equation to get goals. I'm sure Joe will be part of that.”
Mason made a bright start to his Wolves career after he scored on his debut against Bolton Wanderers.
He also added another goal in his next match against Preston North End, but he has not hit the back of the net since.
Mason’s failure to make a big impact at Molineux thus far has not helped Wolves as they have looked to climb up the table.
The Midlands side are stuck in 12th place in the Championship standings and they look destined to finish in mid-table.
