Watch: Dortmund's Reus scythed down by goalkeeper in horror challenge

Marco Reus was cruelly chopped down by goalkeeper Jaroslav Drobny en route to likely bagging Borussia Dortmund's second in its trip to Werder Bremen on Saturday.

The 27-year-old, who only made his season's bow in November after a long layoff with a tear in his abductor muscle, was able to continue after the kick.

Andre Schurrle opened the scoring for Dortmund after five minutes.
