Former Tour de France winner Jan Ullrich will find out in January whether he'll get a lifetime ban from cycling for links to doping.
The Court of Arbitration for Sport says it expects to rule ''in approximately six weeks'' on an appeal filed by the International Cycling Union.
Cycling's governing body challenged the Swiss Olympic committee that dropped an investigation into Ullrich's links with Operation Puerto, a 2006 Spanish probe into doping in sports.
Ullrich, the 1997 Tour winner, is German but raced with a Swiss license.
Swiss officials said last year they have no authority over Ullrich because he retired in 2007.
Ullrich served a six-month ban in 2002. A second doping conviction could mean a life ban from working in cycling.
