The Terriers face a make-or-break Championship play-off semi-final, second leg at Sheffield Wednesday on Wednesday after a goalless first leg in West Yorkshire, with the victors set to face Reading at Wembley on May 29.
The tie, between local rivals, also featured some predictably robust moments with Huddersfield full-back Tommy Smith the game's first yellow card, just before the half-hour, for upending Steven Fletcher.
Ward aside, Town boss David Wagner will probably name with the same team. The match starts at 12:00 on 14 May 2017. It was the home side who dominated possession in the early stages.
It was a tight and cagey affair throughout. The ball fell unexpectedly to Izzy Brown in the area but his half-volley came back off the crossbar. Their first real attack of note came shortly before half-time as Jack Hunt found some space on the left wing but he could not get the ball under control.
Huddersfield go into the play-offs on the back of three defeats from four games and defender Christopher Schindler knows they will need to be better at both ends to turn the tables on Wednesday.
In contrast, it was a classic containing away performance from the Owls, who failed to muster a shot on target and showed little ambition to win the game.More news: James Comey's dismissal: Differing accounts from Trump officials
Ross Wallace found space on the right in the 51st minute and his cross was bound for Adam Reach until covering Huddersfield forward Kachunga made an excellent defensive header over his own bar.
We have to go there and maybe be a little bit more clinical and create maybe a couple more clear-cut chances, Wells told the Huddersfield Examiner.
"Fernando is a player who in one second can solve a game".
"But we have to see it as a normal game".
That turned out to be the best moment for either side in the first half, as although Wagner's men dominated the ball and territory, Wednesday's resolute defending prevented them from creating anything remotely risky.
Wednesday supporters will fancy their chances of securing a trip to Wembley on Wednesday.
Huddersfield have now not scored in four successive matches against Wednesday, last season's losing play-off finalists, so Carlos Carvalhal's side will take heart from this result.
