Newcastle's Fabian Schar was knocked out cold after a clash with Arsenal's Eddie Nketiah.
The Magpies hosted the Gunners in a crucial clash at St James' Park, that remained goalless at half-time. Early in the second period a clearance was headed away by Schar, but not before Nketiah had challenged him in the air. The defender hit the deck and was knocked out.
His closest teammates quickly gestured for medical assistance as the Swiss defender laid motionless on the ground. Staff were quick to the scene and the defender was able to stand up within a couple of minutes. He was helped off the pitch as Jamaal Lascelles came on to replace him in what was a concussion substitution.
