Luke Keary suffered only a cut to his face in the loss to Cronulla and not the latest in a string of head knocks, says Sydney Roosters coach Trent Robinson.
Teammate Lindsay Collins accidentally struck Keary as the pair attempted a two-man tackle on Cam McInnes in the final minutes of the Sharks' 38-30 win on Saturday night.
Keary clutched at his head on the ground but made it to his feet, with medical staff attending to the bleeding above his left eye.
The 32-year-old left the field for a head injury assessment and did not return as fewer than four minutes remained in the Magic-Round clash.
The sight of Keary on the turf was enough to send a scare around Suncorp Stadium given the veteran's history of head knocks.
He suffered five concussions between January 2018 and May 2019, missed more than a month of the 2022 season after another blow to the head and went down again in the round-two loss to Manly in March.
But Keary, who is retiring at the end of the season, spoke to Robinson in the Roosters change rooms at fulltime to reassure him there were no concerns this time.
"I walked in and saw him and he said, 'I'm fine'," Robinson said.
"He's always been honest about where he's at. He walked back in and said he was fine. You can see the cut above his eye."
Keary passed his head injury assessment and will be available for next Saturday's clash against Canberra.
Robinson wants to see tighter defence and fewer errors coming out of trouble in that game.
"You shouldn't ever leak 38 points, that was really disappointing," he said.
"Our game at the moment, you cannot offer opportunities coming out of your own end, as many as what we did.
"It's such a big part of our game and we just opened the door a lot in that second half."
