England wicket-keeper batsman Jos Buttler and Test captain Joe Root became the latest players from the visiting camp to be struck by a flu-like illness on their ongoing tour of South Africa on Saturday, 28 December.
Buttler, who made just 12 off 39 in England's first-innings collapse of 181 in the Boxing Day series opener in Centurion, did not don the gloves on day three, and was replaced by Jonny Bairstow. Root, who made 29 from 49, left the field after the first hour of play, and although he returned later, looked visibly ill.
Ollie Pope, Chris Woakes, Mark Wood and Jack Leach, along with two staff members from the England camp, have already been affected by the illness, while paceman Stuart Broad recovered in time to play the Test.
South Africa, too, were dealt a major blow today, when their opening batsman Aiden Markram was ruled out of the remainder of the Test series with a fractured finger.
The hosts posted 284 in the first innings. They are currently batting, and have taken their lead to well past 250.
