Fabricio Werdum was bounced out of the Strikeforce Heavyweight Grand Prix by Alistair Overeem in June.
Since then Werdum has had rumors swirling about him possibly returning to the UFC, following in the footsteps of other Strikeforce fighters.
Werdum has already picked out his first opponent: former Ultimate Fighter 10 contestant Brendan Schaub.
“Brendan Schaub, I’m ready for you. Anytime, anywhere," Werdum tweeted on Monday. “Great fight for the UFC fans."
Schaub was last seen being knocked out in the first round at UFC 134 in Rio by Antonio Rodrigo Nogueira. Before that, Schaub had not lost a fight since his TUF Finale match against Roy Nelson for the TUF 10 title.
Overall Schaub is 7-3 with a win over Gabriel Gonzaga and a "Knockout of the Night"-winning knockout of MMA legend Mirko Cro Cop at UFC 128.
Werdum went 2-2 in his last stint in the UFC, beating Brandon Vera and Gabriel Gonzaga. Werdum lost his first fight to Andrei Arlovski and lost his final fight against a young Junior Dos Santos by knockout.
Since Werdum's last UFC he has gone 3-1 in Strikeforce with his only loss being his June loss to Overeem.
