Ngidi, who has 55 Test caps for South Africa at an average of just 23.14, was ruled out after undergoing a medical assessment as part of his structured conditioning period, during which scans revealed tendinopathy bilateral of the proximal adductor.

A Cricket South Africa (CSA) statement said he will now begin a rehabilitation program and is expected to return to action in January.

Ngidi will miss the upcoming two-Test series against Sri Lanka and the inaugural all-format tour with Pakistan.
