We investigate whether angular momentum transport due to unstable pulsation
modes can play a significant role in the rotational evolution of massive stars.
We find that these modes can redistribute appreciable angular momentum, and
moreover trigger shear-instability mixing in the molecular weight gradient zone
adjacent to stellar cores, with significant evolutionary impact.
