Cubs fan Ronnie Wickers, aka “Ronnie Woo Woo,” is facing surgery on his left knee after a nasty spill this week at Wrigley Field.
Wickers, who wears a Cubs uniform and shouts, “Cubs, woo!” in a routine he began in the Wrigley bleachers in the 1960s, is on crutches but reportedly feeling better.
He might be out of action for two to three months, according to sources close to Wickers.
Wickers is not employed by the Cubs.
