The 20-year-old is currently on a season-long loan spell with the Bundesliga club and has had a bright start to life in Germany. He's started four league matches so far following his move late in the transfer window.
However, during their 3-2 defeat to Augsburg on Sunday, he suffered a serious injury not long into the second-half. Van den Berg attempted to block a shot from Mergim Berisha but sustained a nasty ankle injury in the process.
The youngster received treatment on the pitch before he was stretchered off and the club has since confirmed he has been taken to hospital. Schalke shared in a tweet: "Sepp van den Berg is on the way to the hospital with a suspected ankle injury. We keep our fingers crossed for you, Sepp!"
