Measurements in the slightly overdoped superconductor TlSr2CaCu2O6.8 at both zero magnetic field and high fields up to 28 T were made. It was found that the reduction of the Knight shift and 1/T1T above Tc is strongly field dependent and follows a simple scaling relation. Overall, the results indicate that an electron correlation-driven pseudogap would terminate at some doping level before entering the overdoped regime.
