  Let $p$ be an odd prime and let $\mathcal{F}$ be a fusion system over a
finite $p$-group $P$. A fusion system $\mathcal{F}$ is said to be nilpotent if
$\mathcal{F}=\mathcal{F}_{P}(P)$. In this paper we provide new criteria for
saturated fusion systems $\mathcal{F}$ to be nilpotent, which can be viewed as
extension of the $p$-nilpotency theorem of Glauberman and Thompson for fusion
systems attributed to Kessar and Linckelmann.
