75 min: Bowen converts from almost in front - Cowboys 30-28.
74 min: As far see-sawing struggles go, it doesn't get any better than this. The Cowboys level the scores after a try to Ashton Sims, yet another four-pointer coming from a kick. 28-all.
70 min: Walsh just off target with the kick.
69 min: The lead changes hands again when winger Josh Mansour, in only his third NRL game, scores in the corner. Panthers 28-24.
66 min: Walsh converts from the sideline. 24-all. Big finish coming up.

59 min: Panthers go further behind after a Bowen penalty goal. Cowboys 24-18.
54 min: Austin converts - Cowboys 22-18.
52 min: A distraught Tariq Sims, the Blues' 18th man, is taken off the field in a medicab with a suspected broken leg after colliding with Penrith's Cameron Ciraldo. Terrible news for Sims and the Cowboys. Moments later, Burns scores for the Panthers. Cowboys 22-16.

48 min: Cowboys go further ahead with a try to former Panther Gavin Cooper after a pinpoint grubber kick from five-eighth Michael Morgan.

Half-time: Panthers 12-10. This truly is anyone's game but I favour the Cowboys if they improve their discipline (the Panthers lead the penalty count 6-3). No doubt coach Neil Henry will impress that upon them during the break.

3 min: Penalty to the Cowboys and they find touch about 40 metres out from the Panthers' line.
1 min: Panthers kick off.
Good evening all. Can the Cowboys win without Thurston and three other Origin stars or will the Panthers pick up where they left off on Monday night, when they defeated the Dragons in golden point? As that great rugby league tragic Bob Marley once said, only time will tell.
The Panthers have made one change to their original line-up with Luke Walsh returning from injury to play halfback instead of Travis "the Texas Terrier" Burns, who moves to the bench. Matt Robinson drops out of the 17. The Cowboys will be 1-17.
