The NRL has cleared Brisbane of any wrongdoing over their handling of Alex Glenn's concussion against Cronulla in the season opener on Thursday night.
Glenn clearly suffered an injury in a 36th minute head clash with Sharks forward Sam Tagataese, and initially played the ball after being spoken to by a trainer.
However, after appearing to attempt to return to the Broncos' attacking line, he was taken from the field for an assessment and subsequently ruled out for the match.
"A trainer ran on to the field to attend to him while the Broncos' doctor reviewed vision of the incident at the NRL's sideline injury surveillance unit," a league statement read.
"Glenn was removed from the field about 35 seconds after his original assessment from the club trainer.
"In that time he did not make any hit ups or tackles. In fact he did not come into contact with any opponent."
The back-rower will have to undergo an internal medical review to be cleared to play North Queensland in Brisbane next Friday night.
The controversy comes in the same week it was revealed former Newcastle winger James McManus has launched legal action against the club for their handling of his head injuries.
McManus was forced to retire last season, well after he played his last NRL match against South Sydney in round 20 of 2015, when he suffered a concussion.
Newcastle have since denied any wrongdoing in the matter.
