T-Mobile's string of injured riders keeps on growing - the newest addition to the list is sprinter Olaf Pollack. Knee problems make him doubtful for his planned starts at Gent-Wevelgem and Paris-Roubaix this coming week. The German is being treated in Potsdam by sports doctor Ralph Schürer. "It doesn't look good right now," Pollack said. "But I'm still hopeful." Pollack has earned both of T-Mobile's wins this year.
