  In addition to the final-state interactions, $J/\psi$ nuclear production
might also be affected by parton energy loss. Using the upper limits from
Drell-Yan data at SPS and Fermilab energies, we estimated energy loss
contribution to $J/\psi$ production in p-A collisions. The results indicated
that the effects might be sizeable at 200 GeV while remaining small at higher
energies.
