Sam Cane has been cleared of a dangerous tackle after an incident at the weekend.

Chiefs captain Sam Cane is free to line up against the Western Force on Saturday after being cleared of a dangerous tackle by SANZAAR.

The openside flanker was cited after he put a crunching hit on Jaguares prop Nahuel Tetaz Chaparro in the 64th minute of last Saturday's match in Buenos Aires. Chaparro required plenty of medical attention and was then forced to leave the field.

SANZAAR's ruling says the incident was "an unfortunate combination of Mr Cane joining to create a maul in a permissible manner at the same time as Mr Chaparro fell rapidly to the ground".

The contact between the two players was unintentional and could not be described as a tackle because Chaparro was not carrying the ball, the judicial committee found.

Unable to find any other type of foul play in the incident, the committee dismissed the citing.

Referee Chris Pollock didn't impose any punishment at the time, despite the incident being replayed on the Jose Amalfitani Stadium numerous times.

Cane has said he had no intention to injure Chaparro, and that the collision with the head was an accident. He had managed a quick glance at the replay on the big screen.

"I was just coming in to try and clean him out around the rib area," Cane said.

"I think, as I'd committed, the tackle was sort of going to ground, obviously it looks like I may have been in contact with his head. No intention to hurt or no malice, hopefully he's doing all right, I spoke to some of the Argentinian media and they said he was all right, so that's good to hear."
