England's patient waiting game continued last night over the potential fall-out from the Dan Luger 16th player saga.

The Six Nations champions will not discover until today whether or not they will be punished over the Luger episode.

World Cup organisers say they have now received all the necessary documentation in relation to the incident.

A rap over the knuckles or a fine would be the probable options, yet another day's wait is hardly helping preparations for their final group game against Uruguay in Brisbane on Sunday.

''The Rugby World Cup tournament director has now received the necessary documentation in relation to England fielding an extra player during the closing stages of the match against Samoa in Melbourne on Sunday,'' said a statement released by RWC in Sydney.

''A decision on any further action is expected tomorrow (Wednesday).''

World Cup chiefs must establish whether or not England deliberately ignored a match official over the Luger episode.

Substitute Luger appeared on the pitch for around 30 seconds before he was ordered off by referee Jonathan Kaplan during England's 35-22 victory against Samoa in Melbourne two days ago.

It meant that England briefly had 16 players on the pitch in second-half injury-time, and led to World Cup tournament director Fraser Neill requesting an explanation from them. Head coach Clive Woodward had earlier pledged that England would ''fully comply'' with the World Cup investigation.

England, meanwhile, lodged an official protest against one of the match officials about what World Cup organisers termed ''a related issue''.

''It was an error, I can assure you, and yes, there has been an investigation,'' said Woodward. ''I would like to think that if any team made an error like this, that there has got to be an inquiry and no more than that.''

South African referee Kaplan and the touchline official submitted reports to match commissioner Geoff Shaw, and Shaw was subsequently in contact with Neill, giving his version of events.

''I don't know how serious this enquiry is going to be, I just know the facts from our side of things,'' Woodward said this morning.

Samoan coaches John Boe and Michael Jones, meanwhile, have consistently said that from the South Sea Islanders' perspective, they view the matter closed and want to move on.

England issued a statement saying: ''The England squad has received notice of a Rugby World Cup investigation being conducted into the circumstances concerning the England versus Samoa fixture played on October 26.

''It is co-operating fully with the investigation, but rather than potentially prejudice the content or conduct of the investigation it will not be making any further comment until all the elements relating to it have been completed.''

Woodward is due to announce his starting line-up for the Uruguay clash at England's Gold Coast base this morning, local time.

Bath pair Mike Catt and Danny Grewcock are likely to make their first starts of the tournament, while Leicester forward Martin Corry could also feature.
