Levi Leipheimer was selected yesterday to replace Lance Armstrong on the U.S. Olympic men's road cycling team.

Meanwhile, the mystery of who will fill the women's mountain biking spot in Athens remained unresolved.

Leipheimer, 30, will make his first Olympic appearance. He was selected over Floyd Landis and Fred Rodriguez to fill the spot Armstrong gave up last week to spend time with his three children.

"Levi's addition to the team is an obvious testament to the depth of American cycling talent," USA Cycling CEO Gerard Bisceglia said. "Lance's departure is understandable and we certainly respect his decision to withdraw himself from the Olympics. Having the luxury to replace him with someone of Levi's caliber allows us to maintain a powerful team with a proven veteran."

Like three of his Olympic teammates -- George Hincapie, Bobby Julich and Tyler Hamilton -- Leipheimer is in the Tour de France. Through 10 stages he was in 19th place, 10 minutes 50 seconds behind France's Thomas Voeckler.

Leipheimer was third in the 2001 Tour of Spain, and finished fourth that year in the time trial at the world championships. That merited him consideration to ride in the time trial in Athens, Bisceglia said.

"We had a few strong cards to play, but given the results of Tyler and Bobby in recent times, they are definitely deserving of the challenge," Bisceglia said.

Meanwhile, USA Cycling officials remained stonewalled in their quest to formally nominate the two-man, one-woman mountain biking team, an announcement that had been scheduled for Tuesday and now will not occur until at least today.

While Jeremy Horgan-Kobelski and Todd Wells are assured of riding in the men's race in Athens, the women's spot -- which is going to either Sue Haywood or Mary McConneloug -- still hasn't been formally awarded since the International Cycling Union hasn't updated its official world points rankings.

Australia's Eadie Is Out

Former world champion Sean Eadie was cut from Australia's Olympic team when Cycling Australia withdrew his nomination because of an ongoing doping investigation.

Eadie's spot on the Australian team was given to Ben Kersten, 22.

Eadie was issued an infraction notice Monday alleging that the Australian Customs Service in 1999 intercepted a package addressed to him that held 16 tablets containing anterior pituitary peptide -- a growth hormone.

Eadie said he had no knowledge of the packages and has already filed an appeal against the infraction notice in the Court of Arbitration for Sport.
