Dortmund's striker Mohamed Zidan could be facing a long spell on the sidelines as he picked up a serious injury in his ribs against Udinese in the UEFA Cup on Thursday. The Egyptian player had to quit the game after only five minutes and he was immediately taken to hospital. It was a real nightmare for Jurgen Klopp as his men conceded a 2-0 defeat at home courtesy of two first half goals from Antonio Flores, 8, and Gokhan Inler, 35. The Bundesliga side exerted lots of efforts in the second half but that wasn't enough to get anything out of this game.
