George North has said that he is "feeling okay" after being knocked out by a blow to the head in Northampton Saints' win over Wasps in the Aviva Premiership.
The winger was left motionless after taking a knee to the head from Nathan Hughes during last night's 52-30 victory, which resulted in a red card for the Wasps forward.
The Wales international wrote on Twitter: "Thanks for all the messages. Feeling OK, up and about."
North missed Wales's second match of the Six Nations last month after sustaining a concussion.
