Day two of the Floyd Landis hearing brought further clarification as to who each side may call to testify before the arbitration panel during the upcoming week. Most of the potential witnesses come from the scientific world, but there are a few names more familiar to cycling fans.

Among them is Greg LeMond, the first American to win the Tour de France, and a vocal critic of doping in cycling. LeMond won the Tour title in 1986, and then two more times in 1989 and ’90. He was listed on the USADA side of the ledger, one spot above former pro cyclist Joe Papp.

On Monday, USADA lead counsel Richard Young said that Papp would be brought before the panel of three arbitrators to explain how he used – and benefited – from testosterone during his racing career.

The Landis list includes Allen Lim, who has worked extensively with Landis in a coaching role and has a doctorate in exercise physiology.

Five-time Tour de France winner Eddy Merckx is also a potential Landis witness. He’s listed as a world-class cyclist and expert in cycling tactics. The reasoning is that if Merckx is called, it will be to address Landis’s startling ride on stage 17 of last year’s Tour when he won the stage took back nearly all the time he’d lost a day earlier.

Retired pro cyclist John Eustice is also on the Landis list.
