When the St. Louis Battlehawks host the home opener this Sunday, Dwayne “The Rock” Johnson says he’s expecting a big crowd. Not just a big crowd –– but the biggest crowd in the XFL this season by a wide margin. He’s expecting 30,000 fans on Sunday at 3 p.m. when the Battlehawks take the field against the Arlington Renegades in The Dome at America’s Center.
