The NRL will hold a triple-header in Brisbane next month as NSW's Covid outbreak continues to play havoc with the competition's schedule. The August 7 action at Suncorp Stadium kicks off with the Warriors facing Cronulla, before mouthwatering clashes between the Sydney Roosters and Penrith and premiership favourites Melbourne taking on Manly. The revised schedule for Rounds 20 and 21 also includes matches in regional centres Mackay and Rockhampton as Queensland plays host to the competition due to NSW's ongoing lockdown. 'I'd like to thank the clubs and the broadcasters for their willingness to see these games in Mackay and Rockhampton eventuate,' NRL chief executive Andrew Abdo said.
