Canberra Raiders five-eighth Jack Wighton is refusing to let any off-field distractions stop him from doing everything he can to end their four-game losing streak. The Green Machine desperately needs to turn things around ahead of their clash against fellow-strugglers Newcastle at Wagga Wagga on Saturday. But they had an unwanted distraction over the weekend when the wife of Raiders lock Joe Tapine posted comments critical of Canberra coach Ricky Stuart on social media. It's the last thing they need as they look to get their season back on track. Kirsten Tapine said Stuart's "interchanges are killing us", referring to the amount of time her husband spent on the bench during the 14-point loss to South Sydney.
