Konta secured her second WTA Tour crown of the year on Saturday with a straight-sets defeat of Caroline Wozniacki at the Miami Open.
But any momentum gained from that triumph may have been stalled somewhat with the news of the world number seven will play no part in the Premier clay-court event in Charleston.
“I’m very sorry to have to withdraw from Charleston, this is a great tournament and I was really looking forward to taking part,” Konta said.
“I was battling a slight shoulder injury and sickness during Miami which has taken hold since the end of the tournament.”
