Sport was overshadowed today by a series of alarming medical and safety scares. Manchester United great Sir Alex Ferguson was taken to hospital as a precaution after falling ill at Old Trafford before the Liverpool match, while Chelsea teenager Jesse Derry was also hospitalized for assessment after a head clash on his Premier League debut against Nottingham Forest. Away from the pitch, concern deepened over imprisoned Iranian Nobel laureate Narges Mohammadi, who was moved from jail to hospital after what supporters describe as a severe cardiac crisis, renewing calls for her release. In Germany, authorities in Leipzig arrested a driver after a car ploughed into pedestrians in the city centre, killing two and injuring several others, though police say there is no further danger and the motive remains unclear. Amid the grim headlines, sport itself still delivered drama, with Wu Yize holding a slender 13-12 lead over Shaun Murphy heading into the decisive session of the World Snooker Championship final.
