A chiral constituent quark model approach, embodying s- and u-channel exchanges, complemented with a Reggeized treatment for the t channel is presented. A model is obtained allowing data for \ensuremathπ^\ensuremath-p\ensuremath→\ensuremathηn and \ensuremathγp\ensuremath→\ensuremathηp to be described satisfactorily. For the latter reaction, recently released data by the CLAS and CBELSA/TAPS Collaborations in the system total energy range 1.6\ensuremath\lesssimW\ensuremath\lesssim2.8 GeV are well reproduced by the inclusion of Reggeized trajectories instead of simple \ensuremathρ and \ensuremathω poles. The contribution from ``missing'' resonances, with masses below 2 GeV, is found to be negligible in the considered processes.
