We analyze the mixing of the scalar glueball with the scalar-isoscalar
quarkonia states above 1 GeV in a non-local covariant constituent approach.
Similarities and differences to the point-particle Klein-Gordon limit and to
the quantum mechanical case are elaborated. Model predictions for the
two-photon decay rates in the covariant mixing scheme are indicated.
