'Expendables 4' Movie Release Date And Casting News:  Sylvester Stallone may not appear in "The Expendables 4."

According to rumors, wrestling star Hulk Hogan will replace Sylvester Stallone as Barney Ross in the upcoming sequel to the action hero franchise. Barney Ross, the leader of the Expendable group of mercenaries was played by Stallone in the previous three installments.

Terry Crews, who played the role of Hale Caesar in "The Expendables" told Slash Films that Stallone might be too busy making the upcoming "Creed 2."

"He might. He might, but whatever Sly says I'm doing. He's like my dad," Crews told Slash Films.

"He's literally my dad in the business. If Sly's like, 'I'm out of this thing,' I don't see myself doing it."

"Expendables 4" cast rumors also include Manny Pacquiao, Mel Gibson, Antonio Banderas, Harrison Ford, Randy Couture, Dolph Lundgren, Wesley Snipes, Ronda Rousey, Terry Crews, Jet Li, and Kellan Lutz.
