In his post-fight interview Nurmagomedov, who is regarded as one of the best fighters outside the UFC, made no mention of possible opponents he would like to face next.
Other than a trilogy fight with Irishman Paul Hughes, who lost on points to Nurmagomedov in two close five-round fights last year, there are no standout contenders.
Another option for Nurmagomedov could be Rabadanov, but it is rare for fighters who train at the same gym to fight each other.
The most enticing fight for Davis next is also Hughes, who has not competed since defeat by Nurmagomedov in October.
Davis will not be able to defend his 2025 tournament crown because the PFL is not continuing the format in 2026.
