Leipheimer was Armstrong's teammate for five years during stints with the U.S. Postal Service, Astana and RadioShack teams before joining Omega Pharma-QuickStep this season.

The team said in a statement issued earlier today that Leipheimer's contract was terminated in "light of the disclosures." It commended the rider for his "open cooperation with USADA and contribution to cleaning up the sport of cycling."

Leipheimer is serving a reduced six-month suspension for doping violations.

According to a team spokesman the decision to fire Leipheimer has the full support of the team owner and the board represented by Bessel Kok and team manager Patrick Lefevere.
