A fuming Melbourne Storm have reportedly contacted the NRL over two Manly players allegedly returning almost two minutes early from the sin bin.

Already seething over their 24-4 defeat, The Storm complained that Manly five-eighth Dylan Walker and teammate Api Koroisau, who were sin-binned for their role in a second-half brawl, returned before the full 10 minute penalty had lapsed.

Melbourne’s Curtis Scott also was sent off for throwing a flurry of punches at Walker in Saturday night’s fiery AAMI Park clash.

Fox League reported that the Manly players returned to the field 1min 41 seconds early.

They also said Storm chief executive Dave Donaghy had phoned NRL boss Todd Greenberg and head of football Brian Canavan before the end of play about the stuff-up.

While both coaches said they weren’t clear on what happened, Storm general manager of football Frank Ponissi confirmed the error.

But Ponissi said that given the 24-4 scoreline, it was unlikely they would take it further.

“It was obviously an error and he made a mistake but I personally don’t want to dwell on it,” Ponissi said.

“He made a mistake and, hopefully, it doesn’t happen again.”

The NRL issued a statement post-match saying it would investigate:

“The NRL will conduct a full review of the timing of the dismissals and the process.

“The responsibility of the timing for sin bins is held by the clubs, although in this instance, it appears there were no club supplied sin bin operators present at the venue.”
