NRL officials are investigating suggestions a Canterbury player hurled a water bottle at Souths prop Nathan Brown as he attempted the last conversion of the game on Friday night.

Apart from suffering a third straight defeat against Souths, the Bulldogs now face a nervous wait to see if one of their players is charged by the NRL match review committee.

Only last year George Burgess was suspended for two weeks for tossing a water bottle at Roosters rival Dylan Napa as he sat on the Rabbitohs interchange bench.

Asked about the incident Brown said: “I didn’t take any notice but all the boys have been saying somebody threw a bottle.”

An ANZ Stadium spokesman said, after reviewing security footage, the bottle had not come from the crowd.

Which leaves only Canterbury players who were grouped on the tryline, watching as the departing bookend was given a shot.

So did it come from the Dogs?

“I dunno. I think so,’’ Brown said.

“It was weird. I don’t know who threw it or what happened. (Laughs) Somebody said it might have been George again. We just took it as a bit of a laugh.”

Souths star Sam Burgess said he hoped no action was taken.

Asked if there was talk of a bottle being thrown at Brown he said: “I hope not for the sake of the players involved. I hope everyone is free to play. These things can be made a big deal of sometimes. Let the game do the talking.”
