"The Silent Assassin," who has been a free agent since an October win over Patricky Freire, voiced his frustrations on Twitter early Thursday morning.
I dont know if I can stay quiet any longer , I am very close at just saying F!@# it !!! Sry 4 all the BS guys, things will get figured out
— Edward Alvarez (@Ealvarezfight) January 3, 2013
Alvarez also tweeted: "Guys its not Up to Me , Who I fight for ,Trust Me" regarding his ongoing contract struggle.
The 28-year-old fought his way to a 9-1 record under the Bellator banner, with his sole loss being a championship bout against Michael Chandler at Bellator 58 in November 2011.
Since then, he has knocked out two other respected lightweights in Shinya Aoki (avenging a December 2008 loss) and Freire.
The UFC first offered Alvarez a contract in mid-December, just over two months after his Bellator contract expired, before his most recent employer entered a counter-offer.
Given Alvarez's reaction, it appears that negotiations are not going swimmingly at all.
