The former Silver Ferns captain is struggling with a calf injury and is uncertain whether she will play in Wellington today.
Wilson hobbled off during the final quarter of the Steel's 48-39 loss to the Magic in Invercargill on Monday and, as a precautionary measure, limited her training this week in an effort to manage the injury.
"I'll definitely be warming up . . . and see from there," Wilson said when asked if she was fit to play.
"Obviously, it is a pretty important game for us so we will need to have all hands on deck if possible."
The Pulse is a tricky match-up for the Steel. The southern team is expected to win and win well, but there will be no room for complacency.
The Wellington-based side has improved steadily and pushed both the Mystics and the Tactix to the wire.
"You approach a game like this as a final. They've got nothing to lose and we've got to make sure we go out there with that positive vibe.
"We can't look too far ahead because the Pulse have been threatening to win and we don't want it to be against us. We need this win just as desperately as they do."
Wilson is not the sort of person to dwell in the past and has quickly dumped the disappointment which followed the Magic loss.
"A win in the Magic game would have been a huge bonus. But we knew it was not imperative to win that game to make the top four, whereas winning a game against the Pulse is imperative."
The Magic defeat, though, has left the Steel's season perched precariously.
Last season it took nine wins to make the semifinals.
If the same remains true this year, the Steel will need to win five of its remaining six matches, including winning in Australia for the first time.
"The difference from last year is a lot of the Aussie teams are winning and losing to each other. Last year there was more of an obvious split.
"Whether having the same amount of wins this year is imperative or not I'm not sure. But we need to win some of those games against the Aussies, otherwise we're not worthy of being in that top four anyway."
Wilson is halfway through her first ANZ Championship campaign and is enjoying the intensity of the tournament.
"You can't rest because every week there is a big game, whereas in the past [during the National Bank Cup] you knew you had some opponents who weren't going to be as strong."
Despite her old team-mate Temepara George making herself available for the Silver Ferns after a two-year international hiatus, Wilson is not tempted to relaunch her international career.
"[George] is such an amazing player and has so much experience.
If she makes that team it will be a huge bonus for them.
It's a very good thing for New Zealand netball.
"But I'll be cheering loudly for her but from the couch, not the sideline."
The Steel should have too much experience for the Pulse but will be wary of the likes of Jamaican defender Althea Byfield and New Zealand Under-21 centre Camilla Lees.
Byfield has proved useful at disrupting the flow of ball and is the competition's fourth-leading interceptor.
Lees is one of those players who always seems to be in the right place at the right time, making a habit out of swooping on stray ball.
• The Queensland Firebirds will look to cast aside a last-start stumble and attempt to end the Melbourne Vixens' unbeaten run this weekend, AAP reports.
The Firebirds allowed the Adelaide Thunderbirds to third spot on the ladder when they let a lead slip in the dying moments of their clash.
Firebirds vice-captain Clare McMeniman does not want a repeat.
"Because we lost that game last week in the last minute and a-half of the game [we need to] have an understanding of being able to punish a team when you are ahead," she said.
The unbeaten Vixens were pushed to the limit in their two-goal defeat of the Swifts last start and co-captain Bianca Chatfield said there was plenty of room for improvement.
"We just have too many turnovers . . . we need to make sure that every centre pass that we have results in a goal to us," she said.
Chatfield said the team needed shooter Caitlin Thwaites to be on her game again.
"They [the Firebirds] have a very strong shooter, Romelda Aiken, and we hope that our attacking team can shoulder a lot of the load this week because with Romelda it is hard to get those turnovers."
In other matches, West Coast Fever are refreshed after a break week and looking forward to playing a home game against the Thunderbirds on Monday night.
The Fever will look to shooter Caitlin Bassett to continue her good form against a confident Thunderbirds outfit.
"We got a lot of self-belief out of last week's game where we came from behind and shouldn't have probably won," Thunderbirds captain Natalie von Bertouch said.
The Thunderbirds needed to shut down the supply to Bassett.
"We have to stop the feed to Caitlin Bassett, because once it is in the circle it is basically a goal," she said.
The Northern Mystics and the Tactix play in Auckland on Monday.
