South Africa allrounder Chris Morris has been ruled out of the remaining Twenty20 internationals against New Zealand after aggravating a quad injury during the first match in Durban. Morris bowled 3.4 overs on debut and took 2 for 19 before he had to leave the field mid-way through his final over.

"It was the same injury he was struggling with prior to the game," South Africa's team manager Mohammed Moosajee said. "He went through the full fitness protocol, he did his fitness tests and had recovered, but when he was bowling his fourth over, he went for one of those effort balls where he tried to bowl a short ball and that's where he probably aggravated it. He's going to need a recovery period of two to three weeks, so he's out of the series."

South Africa are not going to name replacements either for Morris or for fast bowler Lonwabo Tsotsobe, who was earlier sidelined for three weeks because of an ankle injury.

Dale Steyn, who took 2 for 13 in South Africa's eight-wicket victory in the first Twenty20, was released from the squad for the remainder of the series, while Morne Morkel was included for the next two games. The second Twenty20 is in East London on December 23.
