The decay widths of ρʹ → ππ, ωπ, ρη, ωʹ → ρπ, ωη and πʹ → ρπ are recalculated within the extended Nambu{Jona-Lasinio (NJL) quark model. It is shown that the mass of ρʹð1450Þ meson derived in the NJL model agrees with the one given in Particle Data Group tables but significantly deviates from the recent result of CMD-3 collaboration. Comparisons with earlier theoretical results are presented.
