New Delhi: South African pace spearhead Dale Steyn has been ruled out of the fourth and final Test match against India after failing to sufficiently recover from a groin strain sustained during the opening Test.

"I can confirm that Dale Steyn is not going to be fit. Dale is not playing in this game," captain Hashim Amla said on the eve of the final Test at Delhi's Feroz Shah Kotla Stadium.

The 31-year-old premium pacer experienced a tightness in his groin during the second day of the opening Test in Mohali and was subsequently ruled out of the second and third Tests.

India took an unassailable 2-0 lead in the four-match series after comprehensively defeating the tourists by 124 runs in the third Test. With the win, India also ended South Africa's nine-year winning streak in away Test series.
