We present neutron scattering measurements on powder samples of the spinelFeSc2S4 that reveal a previously unobserved magnetic ordering transitionoccurring at 11.8(2)~K. Magnetic ordering occurs subsequent to a subtlecubic-to-tetragonal structural transition which distorts Fe coordinating sulfurtetrahedra lifting the orbital degeneracy. The application of 1~GPa hydrostaticpressure appears to destabilize this N\'eel state, reducing the transitiontemperature to 8.6(8)~K and redistributing magnetic spectral weight to higherenergies. The relative magnitudes of ordered $\langle m \rangle^2\!=\!3.1(2)$and fluctuating moments $\langle \delta m \rangle^2\!=\!13(1)$ show that themagnetically ordered ground state of FeSc2S4 is drastically renormalized and inproximity to criticality.
