England prop Joe Marler handed formal warning for comment on social media about Australia coach Bob Dwyer .
England prop Joe Marler has been given a formal warning by the Rugby Football Union (RFU) following an offensive post on social media.
Marler made an inflammatory comment about former Australia coach Bob Dwyer on Twitter after he accused Dan Cole of scrummaging illegally during the two nation's Test clash in Brisbane on Saturday.
The prop, who asked not to be included for the tour to the southern hemisphere in order to "recharge his batteries", has subsequently been formally warned by the RFU.
"The RFU can confirm Joe Marler has been issued with a formal warning … following his comments made on social media about formal Wallaby coach Bob Dwyer on Tuesday 14 June," a statement said.
"Marler is extremely apologetic for the comment that was made and deleted it within a few minutes of it being posted on Twitter.
"The warning will be retained on Marler's disciplinary record for a period of five years and may be relied upon in any future disciplinary proceedings.
"The RFU considers this matter closed and will not be commenting further."
It is the latest in a string of controversies involving Marler, who has banned for two weeks after calling Samson Lee of Wales "gypsy boy" during a Six Nations match in March.
In his first appearance following the suspension, the prop appeared to kick Arnaud Heguy in the head during Harlequins' European Challenge Cup semi-final win over Grenoble and was subsequently prohibited from playing for another fortnight.
