Feb 20 (Reuters) - Katusha has provisionally suspended Spanish rider Angel Vicioso for failing to appear at a high-profile doping trial in his home country, the Russian cycling team said on Wednesday. "As of now Vicioso is suspended from all competitions," a Katusha spokesman told Reuters. The 35-year-old is one of several world-class athletes being linked to Spanish doctor Eufemiano Fuentes, who is currently on trial for allegedly masterminding a doping ring.
