rigor/vigor confusion

[Erik Hoover]

Cyclist Floyd Landis, accused of doping violations in the 2005 Tour
de France, received bad news today from an arbitration panel.  So it
goes.

What I found interesting was the apparent error in this phrase from
the ruling:

"The Panel finds that the practises of the Lab in training its
employees appears to lack the vigor the Panel would expect in the
circumstances given the enormous consequences to athletes..."

Oops?
