Cape Town - The Springboks want to make sure they don't get caught out by England scrumhalf Danny Care's quick tap-kicks at Twickenham this weekend.Quick tap-kicks were used successfully by England on their tour of South Africa in June, and Bok defence coach John McFarland said they have to be better prepared come Saturday."England's quick tap-kicks are a big threat, especially with a guy like Danny Care who's quick out of the blocks when the referee plays advantage and then awards the penalty," McFarland told Die Burger's website."England's best passages of play last weekend against Australia were also preceded by tap-kicks. They didn't go for posts, but still got huge momentum and created opportunities to score points."We'll just have to be wide awake to the threat Care poses when the referee indicates advantage against us."The clash at Twickenham kicks off at 16:30 (SA time) on Saturday.
