The Eintracht Braunschweig and Borussia Monchengladbach goalkeepers both scored own goals as the Bundesliga sides drew 1-1 on Saturday.
Braunschweig goalkeeper Daniel Davari was the first to put through his own net at the Eintracht Stadion as he failed to collect an inswinging corner and watched the ball hit his thigh and rebound in.

The result means Braunschweig remain rock bottom, while Monchengladbach are seventh.
