England to use goal-line technology if Worcester Warriors trial is a success The Premiership club have introduced the device, called GoalScan, in a bid to remove any doubt as to whether or not a penalty, conversion or drop-goal has gone through the posts. Hereford-based IA Technology Limited has designed a device which generates an electronic curtain which, when "intruded by a rugby ball," transmits a signal to the referee. It will also, if required, activate flashing lights within the bar, LCD units and television monitors. It is hoped that the technology will eradicate mistakes such as the one that occurred in the match between Wales and South Africa at the 2011 Rugby World Cup. James Hook's 14th-minute penalty seemed to go through the posts, but it was not given by the touch judges or referee. Wales lost the match by one point and subsequent replays showed that the penalty had been successful. IA Technology has held discussions with the Rugby Football Union about its new technology and if the trial is successful the company will be to design and build prototypes for trial at Twickenham in partnership with the International Rugby Board. "We have experienced some doubtful decisions here at Sixways Stadium so when I was approached by IA Technology we immediately thought it was a great idea so I contacted the RFU who were also very impressed," said Worcester chairman Cecil Duckworth, whose players will test out the technology at Sixways Stadium on Wednesday. Hopefully it will be accepted by the IRB and I give the project my wholehearted support. London Irish have confirmed Samoa international Setaimata Sa will finally join up with the squad this week. The former Catalan Dragons rugby league star signed a three-year deal last May and will be available for the rest of the season, having secured his UK Visa.
