Kings flank Chris Cloete will be out for the rest of the season after injuring his knee in the 34-18 loss against the Blues on Saturday.
To make matters worse for the Port Elizabeth-based team, openside flanker Cyril-John Velleman will miss a minimum of six weeks after injuring his thumb during the same game.
Stefan Watermeyer is also amongst the wounded after pulling a tendon in his foot. Watermeyer will undergo scans and it is hoped that his injury is nothing more than swelling.
Kings head coach Deon Davids had this to say regarding Cloetes's injury.
"He is seeing the specialist today for scans, should it be the medial cruciate ligament then he will be out for 12 weeks, if it is his anterior cruciate ligament, he will be out for nine months," he told the Kings website.
The Kings have a tough season ahead of them and cannot afford further injuries as they have already been dealt a blow with Schalk Ferreira currently sidelined with a hand injury.
They face up to the Cheetahs in Bloemfontein next weekend before taking on the Sharks in Durban and then doing battle with the Jaguares in Port Elizabeth.
