Schalke came from a goal down to lead against Augsburg on Sunday but conceded a stoppage-time equaliser to stretch their winless run to 27 matches with a 2-2 draw. Marco Richter headed in from close range deep in stoppage time to deny Schalke their first league win since January. Schalke had to endure a nightmare start with forward Mark Uth being seriously injured in the 11th minute after a head clash with Augsburg's Felix Uduokhai. Uth fell briefly unconscious and was put on a drip and rushed to hospital. To make matters worse, Schalke's Suat Serdar scored an own goal in the 32nd minute. But they kept calm and earned a deserved equaliser with Benito Raman's quick break and good finish in the 52nd minute before Augsburg were left with 10 men when Florian Niederlechner was sent off for a second booking. The visitors turned the game around when Nassim Boujellab tapped in a cutback for the lead in the 61st minute. The 21-year-old came close to adding another in the 78th minute but fired over the bar from close-range. Instead, Augsburg got an equaliser through Richter to rescue a point. The result left Schalke in last place on four points. Augsburg move up to 10th on 13 points.
