Richard Bevan, chief executive of the League Managers' Association, admitted they are looking at ways of making improvements to the technical area. On Saturday, Newcastle boss Alan Pardew was involved in a touchline spat with Hull midfielder David Meyler as he tried to recover a ball that had gone out of play.
Pardew thrust his head into Myler's face and now faces a heavy punishment from the Football Association.
Bevan told Sky Sports News: "In the last 12 months we've been reviewing the technical area and we're doing a lot of work on this.
"We'll have talked to over 40 managers and referees as well as looking at other sports such as basketball, ice-hockey, American football, rugby and cricket and seeing how we can help to limit the issues we do get in the technical area from time to time.
"It's not a major problem, as we've only had a handful of incidents this season in over one thousand games.
"But in the Premier League, there are cameras focused on the managers throughout the games but it's important we get out the right message."
Regarding possible changes to the current laws, Bevan added: "The focus is on looking at the physical dimensions, the positioning, the rules of who is allowed in the technical area.
"I'm told Rotherham and Cheltenham are very good in terms of the distance apart and the report will be completed by the end of the season."
