Wales have been told to be disciplined when they finish their Six Nations against Scotland on Saturday.
The penultimate weekend of the tournament saw red cards for England centre Manu Tuilagi and France prop Mohamed Haouas, while Joe Marler and Courtney Lawes were cited.
"You've got to keep your discipline at this level," said Wales assistant coach Neil Jenkins.
It was also confirmed Wales lock Jake Ball needs shoulder surgery.
The Scarlets second-row will miss the next three months after picking up the injury at Twickenham, but full-back Leigh Halfpenny and wing George North should shrug off minor knocks.
Marler was cited by an independent commissioner for the controversial first-half incident with Wales captain Alun Wyn Jones.
The England prop faces a disciplinary hearing on Thursday after being charged with "grabbing, twisting or squeezing the genitals". The shortest ban is 12 weeks, with a top-end level of 24 weeks or more, up to a maximum of 208.
"From my perspective the independent citing commissioner is dealing with that," said Jenkins.
"It's not what we want in the game, but it is what it is.
"They'll deal with it in the right manner and I've no doubt about that."
At the same hearing England lock Courtney Lawes has been cited for a dangerous tackle during his side's 33-30 victory, while Tuilagi will discover his punishment following a dangerous tackle on George North.
Following the events Twickenham, France prop Haouas was dismissed for striking Jamie Ritchie in the face in his side's defeat at Murrayfield, which ended any hopes of a Grand Slam.
"Discipline is a massive part of any sport, but especially at the highest level of Test rugby," said Jenkins.
"You have to understand there are 15 players on either side that are right on the edge.
"You have to keep your discipline amongst it all as it can affect your team's performance. Rugby is incredibly tense, physical and unforgiving."
