Morne Morkel picked up a left side strain while playing his final Test for South Africa in Johannesburg, He left the field 40 minutes before lunch on the third morning but returned soon after and also spent the break between sessions testing if he could bowl again. The team management later said Morkel would receive treatment overnight but they weren't sure if he would be able to bowl again in the match*.
Morkel suffered a similar injury during the first match of a 10 Test summer in Potchefstroom. He was initially ruled out of action for six weeks but only returned 11 weeks later in the domestic T20 competition. Morkel has since been in fantastic form and took a career-best 9 for 110 against Australia last week, which he called the "highlight of my life." He was two balls into his 13th over on Saturday, with figures of 1 for 34, when he handed the ball over to Aiden Markram and jogged off the field.
Pre-series, Morkel announced he will retire from international cricket and is expected to take up a county deal in the coming weeks.
