Chiefs Kingdom is getting yet another huge assist from the Honey Badger ... 'cause top free agent corner Chris Harris Jr. says Tyrann Mathieu's recruiting him HARD to Kansas City!!
"[He says] just come up there, man," Harris Jr. tells TMZ Sports. "Play with him, be able to do what I've done in the past -- play everywhere on the field, and also play with a great quarterback!"
Harris Jr. appears to be on his way out of Denver after spending the last 9 seasons in Mile High .
