The covariant quark model represents an appropriate theoretical framework todescribe the recent results on $B_{s}\rightarrow J/\psi+\eta$ and$B_{s}\rightarrow J/\psi+\eta'$ decays from the Belle collaboration. In thisarticle we present the main features of he covariant quark model together withdetails on some of its aspects and methods, which we consider to be important.Further we apply the model specifically to the studied decay processes and givenumerical results on decay widths as they follow from the odel. We concludethat the model, with most of its parameters previously fixed from differentprocesses, is able to incorporate the new measurements from the Belleexperiment.
