Veteran back-row Lee Gilmour is facing his former club for the first time since being allowed to leave at the end of last season.
However, prop Keith Mason departed in more unsavoury circumstances, seeing his contract suddenly terminated last October with three years still to run on it.
That issue is now with his legal team but experienced Mason, who was left without a club until Castleford signed him for a second time in December, will be keen to remind Huddersfield coach Paul Anderson of just what he let go today.
Bottom-placed Tigers, as a collective, certainly need to get roused as they seek to avoid a seventh successive defeat.
“We did beat Huddersfield here last year and have two of their former players – Gilmour and Mason – who it is a pretty important game for this weekend,” said Millward.
“We know what needs to be done and we have been a bit vulnerable with a couple of players that we’ve had out.
“We need a little bit of luck at the moment but I’ve seen enough this year to show that when we get things right we can do well.”
Castleford, who are chasing an unnamed NRL forward to bolster their ranks, have endured one of the most demanding fixture schedules to date.
Facing a Huddersfield side that has led the competition for long periods does not make their task any easier and Millward conceded: “Last Friday knocked our confidence a little against Wakefield. We got pushed around the middle of the park a bit.
“Keep in mind we didn’t get pushed around by Leeds, Catalans, Wigan and Warrington for most of those games.
“But there are a couple of key areas that we think we need to improve from the two games and improve these against Huddersfield.”
“It is a pretty important month for us with Widnes, Salford and the Challenge Cup all in April.”
The Australian revealed Kiwi centre Jake Webster could be missing for the rest of the season if fears about a need for a knee reconstruction are confirmed.
However, Gilmour is likely to take over from banned Justin Carney at centre and Richie Owen and Jamie Ellis also return.
