England fast bowler Mark Wood is suffering from a heel injury that could cast doubt over his fitness for the next Test.

Wood left the field for treatment and the pain could explain why he was down on pace in this match as he struggled to cause problems for the South Africa batsmen in the second innings. Wood’s career has been beset by injuries and at Lord’s he played his first Test for nearly two years. He said before this game that he was hoping he had put his injury problems behind him and was hopeful he would be able to play three Tests in a row for the first time in his career.

He has developed bruising on his left heel at Trent Bridge but there is good news in the fact England are certain it is not connected to the chronic ankle injury that has required three operations.
