No doubt frustrated at having an enforced rest, Williams provided some highlights in her 10 minutes off the bench, picking up two impressive intercepts.
But with Williams' injury needing to be carefully managed, Taurua will be hoping de Bruin's calf problem is not too serious.
Still, Taurua is fortunate that she has another Silver Fern defender to call on in Sulu Tone-Fitzpatrick.
Consigned to the bench for much of the first half of the competition, Tone-Fitzpatrick got her first start of the season last night at goal keep.
Elevated to the Silver Ferns in 2011 for the end of year tests, Tone-Fitzpatrick has had little game time this season as she has been forced to wait behind Williams and de Bruin.
The young defender relished the opportunity to get back in the circle last night after making cameo appearances at wing defence - a position where she has struggled.
Despite the changes to the line-up the Magic made a strong start, with their attack end picking up where they left off last week in their 16-goal win over the West Coast Fever.
Leading 16-11 at the first break, the Magic made a storming start to the second period, extending their advantage out to nine goals five minutes in to the quarter, before they went stone cold.
Over the next five-minute block the Magic scored just one goal, as the Pulse stepped up their defence throughout the court. Joline Henry was a particular stand-out for the Pulse, playing a hand in forcing several Magic turnovers.
With three minutes to go the Pulse had reduced the deficit to just one goal, with the chance to level the score at 24-all but Camilla Lees was unable to pull in a wayward pass and the ball spilled over the sideline.
That gave the Magic the opportunity to restore a bit of breathing room before the halftime break, as they took a four-goal lead in to the third period.
Again the visitors opened strongly, showing greater fluency in their through court play, and this time were able to build on their lead.
