Abstract: Let $G$ be a finite group and $p$ be a fixed prime. A $p$-Brauer character of $G$ is said to be monomial if it is induced from a linear $p$-Brauer character of some subgroup (not necessarily proper) of $G$. Denote by ${\rm IBr}_{m}(G)$ the set of irreducible monomial $p$-Brauer characters of $G$. Let $H=G'{\bf O}^{p'}(G)$ be the smallest normal subgroup such that $G/H$ is an abelian $p'$-group. Suppose that $g\in G$ is a $p$-regular element and the order of $gH$ in the factor group $G/H$ does not divide $|{\rm IBr}_{m}(G)|$. Then there exists $\varphi\in {\rm IBr}_{m}(G)$ such that $\varphi(g)=0$.
