A goat's head was delivered to Wrigley Field on Wednesday addressed to Chicago Cubs owner Tom Ricketts, a team spokesman confirmed.

No note was included, and it was turned over to Chicago police.

"We got a call at 2:30 p.m., responding to 1060 West Addison, Wrigley Field," a Chicago Police Department spokesman said. "We're investigating it as an intimidating package."

The package was found at Gate K near the field, the team spokesman told the Chicago Tribune.

It's possible the goat's head is in reference to a "curse" placed on the team during the 1945 World Series. Restaurant owner Billy Sianis brought his goat to a game, but was asked to leave and he vowed the team would never win again.

The Cubs lost that series and have never been back. They last won a championship in 1908, the longest drought in professional sports.

The Cubs are currently locked in a tense negotiation with the city and neighborhood regarding the renovation of Wrigley Field and the desire to play more night games. A deal was hoped to have been reached by the start of the regular season but is still being negotiated.
