It is shown that the Pomeron could be regarded as a Reggeized Tensor Glueball with a trajectory of alpha(P)(t) = 1.08 + 0.2GeV(-2)t. Under this theory, the total cross section measured for pp elastic scattering at high energies is reproduced successfully. The best fits to experimental data lead to a Gamma(xi-->p (p) over bar) = 9 +/- 3MeV and Gamma(xi) > 50MeV, and J = 4 for spin of the tensor glueball m(xi)(2230) is precluded.
