We find that available data on $J/\Psi$ photoproduction at $|t|{ \ge}$1 GeV are energy independent over the range $22{ \le}\sqrt{ s}{ \le}170$ GeV and show a very soft $t$ dependence. Through a systematic analysis of the data we detect a new trajectory, which manifests itself at threshold and is energy independent. The trajectory couples to the axial form factor of the nucleon and can reproduce the $J/\Psi$ exclusive photoproduction data at large -$t$.
