Kings duo Luzuko Vulindlu and JP du Plessis will need to pass concussion tests this week in order to be cleared to face the Sunwolves on Saturday.

Both players suffered blows to the head against the Hurricanes in Wellington last Friday, and will be carefully monitored this week.

Meanwhile, coach Deon Davids said Schalk Ferreira and Thembelani Bholi, who had been sent home after the game against the Crusaders, were also being assessed before the game against the Sunwolves.
