The Chicago Cubs will leave WGN after the 2014 season unless the television station agrees to increase fees for 2015 and beyond, according to a report.

Team officials declined to comment on the Chicago Tribune report, which said the team informed the station Tuesday that it would opt out in 30 days if the station didn't agree to its financial concerns.

WGN has televised Cubs games since 1948, currently airing up to 70 games per season.
