  The near-threshold behavior of the ppbar invariant mass spectrum from the
psi(3686) -> gamma ppbar decay reported recently by the BESIII Collaboration is
analyzed. The enhancement in the ppbar invariant mass spectrum near threshold
is nicely reproduced by the ppbar final-state interaction based on the isospin
averaged 1S0 partial-wave amplitude as predicted by the Julich
nucleon--antinucleon model. Contributions from the f_2(1910) or f_2(1950)
mesons, as promoted in earlier works, are not needed.
