Berlin - Suspected doping cases are being investigated in cycling and cross-country skiing, an anti-doping forum was told on Thursday.
The International Cycling Union (UCI) fears more doping cases as blood profiles of cyclists are evaluated, its president, Pat McQuaid, said.
Meanwhile the international ski federation FIS is examining five suspicious blood profiles by cross-country skiers, Swedish doping specialist Bengt Saltin said.
He said it was hoped to release the results of the evaluation within the next four weeks.
McQuaid said a few of the profiles in biological passports introduced by the UCI this year show "irregularities" which could point to the use of banned substances or methods.
