Warriors skipper Simon Mannering says he’s suffered no ill effects from the head knock that forced him briefly from the field during the NRL defeat to South Sydney.

Mannering, playing at lock, looked dazed and had to be helped off for concussion tests after making a tackle late in the opening spell in Perth on Saturday.

He returned for the second half and he says he’s had no problems since the match.

“No, not at all,” he said on Tuesday.

“We even had a pretty long flight back home afterwards and I’m been feeling pretty good the last couple of days and trained all right today, so should be right for the weekend.”

In April, the NRL tightened concussion rules after fining Parramatta over three incidents, including one involving hooker Nathan Peats against the Warriors at Mt Smart Stadium in round three.

The changes include not permitting players to return to the field if they displayed loss of consciousness or memory impairment.

Mannering said he remembered the incident and the game, did all the checks with club doctor John Mayhew and “passed them all pretty easy”.

“I’ve probably hit my head harder in times before,” he said.

“It probably just got a bit of a sweet spot. I had a bit of trouble getting off the ground, but I felt pretty confident coming back on, as did John.”

The Warriors, who dropped to eighth on the back of their 36-4 loss to the Rabbitohs, are at home to the sixth-placed Sydney Roosters on Saturday night.
