England are "holding their breath" over James Anderson's latest side injury.
Anderson, who took seven wickets in England's second Test win against South Africa, has undergone scans on a side injury after struggling through the fifth-day at Newlands on Tuesday.
The England seamer spent time off the field during the afternoon session, and manager to bowl just two overs after tea as the tourists chased the five wickets needed for victory.
Though he was unable to deliver with the ball, Anderson took a catch at leg-slip as Stuart Broad claimed the key wicket of Rassie Van Der Dussen in the final session.
"He's been such a great servant that we're holding our breath and (have) fingers crossed for him," Ashley Giles, director of England men's cricket, told BBC Radio 5Live.
"We'll be desperate if Jim was injured again. He's worked so hard to get back in the team.
"We certainly don't think it's a recurrence of his previous injury."
