We present O-17 NMR measurements on a single crystal of overdoped BSCCO-2212 (T$_{c}$= 82K). As a function of temperature we measure the planar oxygen's: resonance linewidths, Knight shift (K), electronic field gradient (EFG), and spin lattice relaxation rate (1/T1) along each principle axis. Our analysis shows that their temperature dependence can be explained by a suppression of the density of states in the pseudogap region T $<$ T$^{\ast }$ = 94K.
