Titan FC announced the addition of five fighters to the roster, including a pair of UFC veterans.
Steven Siler, Jack May, Andre Harrison, EJ Brooks and James Jenkins all signed fight contracts with the promotion.
Siler went 5-4 during a nine-fight run with the UFC, including a knockout of Mike Brown and decision wins over Kurt Holobaugh and Cole Miller. He was released after three consecutive losses.
May fought twice inside the Octagon, losing both, while FightLine recently featured Harrison, who trains out of New York with the likes of Chris Weidman, Al Iaquinta and Aljamain Sterling.
Harrison was the featherweight champion for Ring of Combat.
Brooks fought earlier for Titan FC, defeating Todd Moore. He has also competed for Resurrection Fighting Alliance and Bellator, while Jenkins is another East Coast fighter having competed for Ring of Combat.
