Kiwis utility Te Maire Martin is out of the game indefinitely with a "small bleed on the brain" — though his NRL club insists the situation is not career-threatening.
NRL.com reported that Martin has been affected by ongoing migraines and headaches over the past two weeks, resulting in him being stood down from this Friday's game with the Titans.
The 23-year-old will meet with specialists and neurologists for more tests.
The Cowboys, at this stage, don't believe Martin's symptoms result from a concussion suffered in training or a game.
"He's OK, he's resting at the moment and that's the only thing he can do at the moment," North Queensland director of football Parr told NRL.com.
