We calculate the $\alpha s$ corrections to the transverse polarization fraction of $\psi^\prime$-s produced at the Tevatron. If the `$\psi^\prime$-anomaly- is explained by gluon fragmentation into a colour octet Fock component of the $\psi^\prime$, the $\psi^\prime$-s should be $100\%$ transversely polarized at leading order in $\alpha
