(NEWSER) – Chicago Cubs fans have long feared a curse on the team after a man with a goat was told to leave Wrigley Field during a 1945 championship game. Perhaps it was that story that prompted the delivery of a goat's head to the team's owner, Tom Ricketts, yesterday at the field. The package, which contained no note, was passed to cops, ESPN reports. "We're investigating it as an intimidating package," police said. The delivery comes amid a feud with locals over Wrigley Field renovations, ESPN notes.
