South Africa lock Eben Etzebeth was cleared of an eye-gouging charge at a disciplinary hearing.
The South African Rugby Union tweeted, "Good news on Eben Etzebeth - he's not guilty and free to play against England on Saturday."
Etzebeth was cited for allegedly making contact with the eye or eye area of Scotland flyhalf Greig Laidlaw in the second half of the 21-10 win over Scotland last Saturday at Murrayfield.
IRB-appointed judicial officer David Martin ruled the contact was accidental and didn't amount to foul play.
The Springboks will name their team on Wednesday (local time) to play at Twickenham on Saturday.
