The tackle was reminiscent of one by Eastwood that ended Penrith rookie Bryce Cartwright's 2014 season after suffering a broken ankle in round 21 of last year's competition, one that doctors feared may prevent him from playing again.

Eastwood is not the only player who uses the tactic, with South Sydney prop Thomas Burgess locking the leg of Bulldogs centre Tim Lafai between his legs and twisting him backwards during the Good Friday clash between the teams this year. Lafai came from the field and was sidelined for six weeks with a medial ligament tear. In another incident last Saturday night, in which Moses Mbye wrapped his leg behind St George Illawarra forward George Rose as he was held by the Canterbury halfback and teammates David Klemmer and Frank Pritchard before being flipped on his back in a tackle some commentators compared with a jujitsu throw.

While Peter Sterling pointed out on Channel Nine that it is legal for a player to use his legs in a tackle provided he has hold of his opponent with both hands, the spate of serious injuries caused by the tactic has raised concerns. "It's up there with the cannonball tackle, we don't need it in the game," Wendell Sailor said during the Triple M call of Saturday night's elimination final.

There is no suggestion that Eastwood or any other player set out to cause injury and the New Zealand forward immediately signalled his concerns for Marshall to referee Gavin Morris after realising he was hurt.

However, the tactic has the potential to cause serious injury and Cartwright revealed in an interview earlier this year that there were fears for his career after the tackle by Eastwood. "He tackled me, my leg got twisted up and the whole thing went numb from my hip down to my foot," Cartwright said. "It was like a car crash. I lost all the cartilage, broke the bone, tore every ligament ... the morning after I did it the entire leg was black." Incident: Tom Burgess wrapping his leg around Tim Lafai in round five. The initial diagnosis for Marshall, who attended Keebra Park High with Eastwood's brother Shane and played alongside him in the 2003 Australian schoolboys team, was that he had suffered a syndesmosis or high ankle sprain which may require surgery. Meanwhile, Pritchard may have played his last match in the NRL after being charged with grade-one dangerous contact for sliding into Gareth Widdop with his knees after the Dragons five-eighth had dived onto a loose ball.
