So too would shoulder charges gone wrong such as then-Brisbane back-rower Ben Te'o's hit on Wests Tigers prop Matt Groat last year.
"It's a decision that Daniel Anderson and his team need to have a greater awareness of using the option of sending players from the field for those types of tackles," said NRL football operations manager Nathan McGuirk.
"There are tackles this year that have resulted in huge suspensions and the referees should be aware that sending players off is an option. The view of the committee is that we need greater awareness for the use of send-offs, particularly with one-on-one lifting tackles which result in a player landing directly on their head and shoulder charges that make forceful contact with the head or neck."
However, the sin-bin will not be used for repeated incidents of serious foul play as in the case of Fa'aoso who was twice placed on report against Souths.
The NRL has also asked Anderson to look at a way of dealing with the increasing prevalence of time wasting.
"The average time taken to set scrums has increased dramatically and that is something we have to be mindful of," McGuirk said.
An option was a time out for scrums similar to the one instituted for drop outs.
