Rugby: Injury sidelines Fourie du Preez

Springbok halfback Fourie du Preez will be sidelined for four to six weeks after tearing a right knee ligament.

The Bulls confirmed Du Preez suffered a grade two medial ligament tear when his knee bent back awkwardly in the defending champions' victory over the Sharks on the weekend.

Du Preez, 29 and a 55-test veteran, should be fit for the start of the Tri-Nations in July.
