According to an MMAJunkie.com report, the UFC has also signed Dennis Hallman, another former Strikeforce fighter. A source close to the UFC intimated more signings might be on the horizon as fighters complete their Strikeforce contracts.
"We wish Phil the best of luck and hope he can revive his career,'' Strikeforce Founder and CEO Scott Coker said in a release Thursday. "If he can, maybe one day, he can return and fight for us."
Strikeforce consultant Bob Cook confirmed to Sherdog.com that Baroni was released from his Strikeforce contract in the past few days and would be free to sign with another promotion.
Baroni (13-11) dropped a unanimous decision to Joe Riggs in St. Louis in June. He had won three bouts in a row before the loss.
