South Africa v Sri Lanka, 1st Test, Centurion, 2nd day December 16, 2011

Mathews taken for scan with groin injury

Sri Lankan vice-captain Angelo Mathews has suffered a groin injury and will have a scan to determine the severity. Mathews bowled five overs on the second day before leaving the field.

Batting coach Marvan Atapattu confirmed that he was taken for an MRI scan but could not comment on Mathews' participation in the rest of the match, saying that information will only be available after the scan has been conducted. Mathews has only just made his return to bowling after suffering a injury to his quadricep during the World Cup semi-final and with Sri Lanka's casualties in that department growing, was expected to play some role with the ball in this series.

Meanwhile, South Africa also have a walking wounded in their ranks. Jacques Kallis was hit on the side of the head by a Dilhara Fernando bouncer that kept low. He was attended to on the field and appeared unable to continue batting but, after a few minutes, resumed.

"The grill of the helmet caused a laceration to his left ear and we had to glue stitch it together," Mohammad Moosajee, South Africa team manager said. "He was a bit dizzy and disorientated at frst but I am happy to report that he is doing much better."

"Whenever the ball doesn't deflect and go back towards the slip cordon, you know it's a hard hit," said AB de Villiers on seeing Kallis get hit. "I knew it would take a few minutes for him to get going but credit to him that he kept going, It was a really important moment in the game. If Ash [Ashwell Prince] had to come in there, you never know what could have happened."

Kallis will be monitored overnight but is expected to be in good health for the rest of the match.
