The longtime UFC fighter is resuming his fight career, but it won't be in the UFC's octagon. Instead, it will be in the Bellator cage.
The upstart promotion announced it had signed Pellegrino, and that he would debut in November.
He will face Patricky Pitbull Freire on November 26 in Atlantic City, New Jersey.
Pellegrino (16-6) had a five-year run in the UFC, fighting 12 times for the promotion. During that time, he went 7-5. From September 2008 to March 2010, he won four straight, moving up the lightweight ranks, but that streak was snapped in a unanimous decision loss to George Sotiropoulos.
In March 2011, he fought Gleison Tibau in his home state of New Jersey, and lost a tight split decision. In early June, after losing those two straight bouts, he announced he was stepping away from MMA.
At the time, his announcement left room for a return, though he said he believed it wasn't likely. Just three months later, the 32-year-old has decided a close to his career is a bit premature.
Pellegrino is 16-6 overall. Freire is 9-2 and recently had a five-fight win streak snapped in a unanimous decision loss to Michael Chandler at Bellator 44.
