Frank Gore says don't rule out seeing him back in the NFL -- 'cause the former RB told TMZ Sports he would be open to a return ... if the right Super Bowl contender called him.
"Ay, ay, I'm ready," Frank said. "Best shape I ever been," he continued. "I just weighed in at 209. Whatever team who pushing for that Super Bowl run, I'm ready to go in."
Of course, we haven't seen Gore in an NFL backfield in almost a year when he last played for the New York Jets .
