Toyota-United's statement:
Frankie Andreu has been relieved of his duties as co-Team Director of
the Toyota-United Pro Cycling Team, it was announced today by Team
Owner Sean Tucker.
"Frankie has contributed greatly to this team's success and helped with
the team's early development. Unfortunately, due to other obligations
and commitments, Frankie was not able to fulfill his contractual
obligations," said Mr. Tucker.
"This left us no choice but to terminate our relationship. We do
wish him only the best as he pursues other interests. Harm Jansen will
continue as Team Director for Toyota-United, and we are fully confident
that Toyota-United will continue to be successful throughout the rest
of the season."
So yes, they fired him for missing one race (a race they won without
his actual presence, so I suppose that makes one wonder just how
crucial he was).
