Molby said: "Gary Alexander and Richie Appleby won't play tonight while Greg Strong is 50-50 with an ankle ligament problem that he picked up on Saturday.
"He has a chance of playing and will have a fitness test before the game. But if he doesn't come through then so be it, we'll just have to get on with things.
"Injuries are part and parcel of the game and we can't use them as an excuse.
"We have had the report back on Bristol Rovers and may make a change or two but won't make a decision until very late on."
The Dane has yet to see the Tigers win, and although he's looking for three points tonight, a draw wouldn't be a bad result.
"We need to pick up a lot more points on the road this season and hopefully we can get the ball rolling tonight.
"Of course, we would accept a point if it came to it but ideally we want all three."
Justin Whittle is set to play if Strong doesn't make it, while new signing Simon Johnson will be in the squad.
Expected line-up (4-3-3): Glennon; Edwards, Whittle, Anderson, Smith; Greaves, Ashbee, Green; Williams, Dudfield, Elliott.
Subs: Musselwhite, Petty, Price, Philpott, Johnson.
