Canberra have survived an error-ridden first half and a Wests Tigers fightback to snatch a 22-18 victory to keep alive their NRL top-four finals hopes.
The Tigers had the chance to steal an unlikely win at the death but veteran winger David Nofoaluma failed to take a Luke Brooks kick on the full and although he kept the ball alive to pass back into Starford To'a, the centre was taken into touch.
However while Raiders coach Ricky Stuart was already celebrating, the tackle on To'a by Jack Wighton was deemed high, giving the visitors an extra play although they were unable to take advantage.
