The hypothesis of the quark Reggeization is tested by taking the high-energylimit of the two-loop amplitude for quark-gluon scattering which was recentlycalculated. The limit is compatible with the Reggeization in the leading andthe next-to-leading orders and allows the determination of the quark trajectoryin the two-loop approximation. The trajectory is presented as an expansion inpowers of (D-4) for the space-time dimension $D$ tending to the physical valueD=4.Comment: 14 pages, LaTeX, JHEP3 clas
