Strikeforce has yet to officially announce the card or any fights signed for it as of Thursday evening.
Rockhold was expected to meet Tim Kennedy in his first title defense, but according to sources, Kennedy couldn't commit to the fight due to an undisclosed injury.
Rockhold (8-1) won the title in September when he defeated Ronaldo "Jacare" Souza via unanimous decision. The American Kickboxing Academy member has won his last seven fights in a row.
Jardine (17-9-2) fought Gegard Mousasi to a draw in his Strikeforce debut in April. This fight would mark his first at 185 pounds. "The Dean of Mean" is 2-1-1 since his release from the UFC in June 2010.
