Captain Paul Robinson and striker Lewis Grabban will both miss the game through injury while midfielder Marc Laird is suspended after picking up five bookings. And Jackett knows that they will be a big loss.
"I've been pleased by the form of all three players," the manager told the club's official website. "They have contributed massively to where we are in the table. But I am confident that we have players good enough to compensate while they are out.
New signing Richard Duffy is expected to come in for Robinson while Chris Hackett and Jimmy Abdou are in line to replace Grabban and Laird respectively.
