  We study the effect of the nucleon meson cloud on centrality dependence of
the jet nuclear modification factor $R_{pA}$. We find that the meson-baryon
Fock components may lead to a noticeable deviation of $R_{pA}$ from unity. Our
results for $R_{pA}$ show the same tendency as that observed by ATLAS in $p+Pb$
collisions at $\sqrt{s}=5.02$ TeV. The meson cloud suppresses the central jet
events and enhances the peripheral jet events. But quantitatively the effect is
somewhat smaller than in the data.
