Sam Warburton has demonstrated exactly how you should clear out a jackaller without causing injury to you or your opponent.
From the Darcy Swain incident in the Bledisloe Cup, to Vaea Fifita's red card against Cardiff Rugby this month, it is evident that clearing out incorrectly can have dire consequences.
Warburton has argued that the jackal should stay in rugby, but the act of clearing out needs some changes.
"What I see too many times is a player coming in, the head goes inside of the rib cage, in which case you can cause a lot of compression on your neck," he said. "You do not want your head in that position."
The so-called croc roll is a technique which has been employed by some players when making a clear out, but it can have unsavoury consequences, as Warburton explains.
"And then the croc roll. This is the lazy way to do it, it's when you haven't arrived low enough, you're too high and he's beaten you. You grab him and you roll him off. We don't want to do that, it's not safe for this player and it's a really slow and inefficient way of cleaning out a jackaller."
The two-time Lions captain went on to explain exactly how you should perform a clear out without posing a risk of injury.
"We need to come in under this armpit at around a 30 degree angle - you won't be done for going in at the side."
Sam demonstrates two key points with the more effective, safer clear out. He lifts the right leg of the jackaller with his left arm, while lifting the shoulder with his right arm, clearing out in one swift movement.
The crocodile roll has become a hot topic recently, with Akker van der Merwe sustaining a serious injury while playing for Sale Sharks. After the match, Ben Kay made a similar explanation on BT Sport.
