Home side seal a stunning last-gasp victory over the Dogs.
Penrith fullback Matt Moylan landed a sideline conversion right on full-time to give the Panthers an 18-16 NRL win against Canterbury at Penrith Stadium on Saturday.
Two second half tries in the space of five minutes had given the Bulldogs a 16-12 lead and they seemed destined for victory.
But the Panthers levelled the scores through a try to winger Kevin Naiqama before Moylan stepped up and calmly landed the sideline conversion moments before the full-time siren sounded.
The Panthers had led 10-6 at half-time.
They opened the scoring early when David Simmons flew high to catch a Jamie Soward bomb and popped a pass for centre Dean Whare to cross in the corner after only four minutes.
Simmons had a four-pointer of his own in the 20th minute when he again flew high to pull down a Soward bomb to give the Panthers a 10-0 lead.
The Bulldogs added their first points six minutes later, when Trent Hodkinson was on the end of a play that started inside his own half and saw a break from Thompson before Josh Morris threw the final pass.
