The teams will collide at 18h00 at Bidvest Stadium.
Wits are a point behind log leaders Cape Town City with 38 points from 19 matches - 14 points ahead of eighth-placed Stars.
“The team spirit is high ahead of the Wits game,” Mwedihanga tells KickOff.com.
“We have rested well and we have played some friendly games to keep us going. We’ve been also working hard in all our games and also the CAF Confederation Cup games.
“We also don’t have any injured players ahead of our game against Wits and the medical team checked everyone. So I think we are ready for the game.”
The Namibia international adds that coach Cavin Johnson has not set a target for the resurgent side in the league.
The Rustenburg-based outfit have won five of their last six games in all competitions, most recently defeating Vipers SC 3-2 in the CAF Confederation Cup on March 18.
“The coach hasn’t said anything for now on how he wants us to finish the league. But he said that we must take each and every game one-by-one and do our level best.”
