Msowoya – who is out of favour at Pirates – has been training with Tuks hoping to join the Pretoria club, possibly on loan.
The striker spent part of last season on loan at Platinum Stars.
Steve Barker, the Tuks coach confirms that they will be making big decisions this week.
"He (Msowoya) is still here and we are having a look at him and we will use the friendly match against Celtic tomorrow as the final assessment. We should have made all relevant decisions by the end of the week so that come next week we start working with players that have already signed with the club," says Barker.
Tuks are in negotiations with Dipsy Selolwane and have already signed Gabonese defender Charly Mossouno and Zimbabwean midfielder Lionel Mutizwa along with Warren Bishop, Thabo Mosadi, David Radebe and Vincent Kobola.
Barker adds that they will spend three to four days in Cape Town at the beginning of next month ahead of the match that they will play against Chippa United on August 4.
"We will play Chippa in a match organised by the Cape Town Municipality pitting the two promoted clubs against each other," he says.
Meanwhile, Tuks have invited Malawian goalkeeper Simplex Nthala for trials as cover just in case the deal to snap up Zimbabwean goalkeeper Washington Arubi doesn't work out.
Arubi is implicated in the Asiagate match-fixing scandal and Tuks want him cleared first by Zifa before completing the move.
"Arubi arrived here today because we want to sign him but we are also aware of the Asiagate scandal. So we hope that by the end of the month this whole thing will have been sorted so that he signs," explains Barker.
