Msowoya and Olomu have both been training with Tuks for the past two weeks in the hope of clinching deals after being transfer-listed at their respective clubs.
"We have had a very good look at Msowoya but we have decided against the option of bringing him on board. At this stage we have also decided not to sign Olomu because he is still contracted to Maritzburg and both players are not training with us anymore," reveals Steve Barker, the Tuks coach.
Tuks have however finally completed the signing of Arubi from Zimbabwean club Dynamos.
Arubi's move had been unsure as Tuks insisted they would prefer to have him cleared from the Asiagate match-fixing scandal first before completing his signing.
However, the club seems to have changed its mind as Arubi remains implicated in the scandal.
"The deal regarding Arubi is done and we just hope to receive the signed agreement from his club today. He has been here training with us for some time now and we actually hope to have him available for our first League match of the season," says Barker.
Barker adds that they have kept two foreign spaces open which they intend to fill up if they find quality players.
The club has already signed three foreigners in Arubi along with his fellow countryman Lionel Mutizwa and Gabonese defender Charly Mossouno.
