ESPN has until Thursday to match NBC Sports Network's seven-year, $20-$23 million per year offer to retain the Big East's media rights, league sources told ESPN.

The Big East received an official offer from NBC Sports Network that will extend both the football and men's basketball media rights through the 2019-20 academic year. The amount per year varies based on any future membership changes for the Big East, sources said.

ESPN, the league's rights-holder, has until Thursday to match NBC Sports Network's offer to keep the Big East's media rights. ESPN has had the Big East's basketball media rights since the conference was formed in 1979.

ESPN spokesman Josh Krulewitz declined comment Friday night.

The Big East's basketball media-rights deal with ESPN and CBS expires after the 2012-13 academic year, while the football deal with ESPN expires after 2013-14.
