George North concussion: Wasps forward Nathan Hughes banned
Wasps forward Nathan Hughes has been banned for three weeks by an RFU Disciplinary Panel following an incident that led to Northampton's George North being knocked unconscious.
The 23-year-old was sent off for his challenge on the winger, who was scoring Saints' second try on Friday.
A panel found Hughes guilty of "striking with the knee and/or shin".
"This was a three-week ban on the basis that no intention was found," said Sir James Dingemans, chair of the panel.
He added: "However, there was recklessness meaning that, notwithstanding the harm, it was a low entry point of four weeks with mitigation of one week to reflect his previous clean playing record."
Wales international North is due to see a neurosurgeon to determine when he is able to play again.
North, 22 has been knocked unconscious three times in recent months.
