The Queensland Maroons and North Queensland Cowboys have been rocked by news that enforcer Matt Scott has suffered a torn anterior cruciate ligament.

The Cowboys' co-captain, who at 31 is among the most experienced in the Maroons' pack, suffered the long-term injury in Friday's Round 2 game against the Brisbane Broncos in Brisbane. 

Scott left the field in the second half and scans over the weekend confirmed the injury. He will now undergo surgery on his knee. 

"It's obviously a huge blow for Matt and he's understandably devastated," Cowboys coach Paul Green says. 

"He'll have surgery then start his rehab, and knowing the type of player and person he is, he'll approach his recovery in the same dedicated way he trains and plays… with 100 per cent commitment." 

It follows news that Queensland teammate Greg Inglis will be sidelined from the State of Origin series with the same injury, while NSW VB Blues winger Josh Mansour is racing the clock to return from his own torn ACL in order to be considered for selection.
