Kiwi Heem gets two-week ban for dangerous tackle
New-Zealander Heem saw red early in the second half of the English Premiership match at Wasps' Ricoh Arena ground in Coventry after taking out Springbok international Le Roux in the air.
He accepted a Rugby Football Union disciplinary charge at a hearing on Monday while the governing body confirmed his punishment on Tuesday saying: "The panel deemed that the actions of Heem were reckless and in part affected by the running line of Wasps' number 13.
"Notwithstanding this, the player accepted his actions merited the award of a red card and the panel, having heard direct evidence from Wasps' Willie Le Roux, found this was a low-end entry point."
Heem is free to play again on April 18.
