While his team mates were training at Schenckendorffplatz, Rune Jarstein underwent an operation. On Wednesday morning, the 34-year-old goalkeeper had key-hole surgery done on his knee. “The operation went well and without any complications. I will be back on the pitch for pre-season,” said the Norwegian national team goalkeeper, who will miss the last two Bundesliga games of the season. Rune has played 31 Bundesliga games this season for ‘the Old Lady’ and has kept eight clean sheets. He also made two appearances in the DFB-Pokal.
