South African bowler Marchant de Lange has been ruled out of his country's tour of England after he suffered a stress fracture to his back.

The 21-year-old's injury comes just days after his teammate Mark Boucher was forced to retire from international cricket after suffering a severe eye injury.

South African physio Brandon Jackson said: "Marchant has been diagnosed with lower-back stress fracture and will require at least six weeks' rest and rehabilitation."

De Lange will be replaced in the South African squad by Albie Morkel.
