WEEI’s John Dennis is reporting that Boston Red Sox General Manager Theo Epstein is no longer the Boston Red Sox General Manager. Epstein has agreed a five year deal believed to be worth more than $15 million with the Chicago Cubs.

According to Dennis, Boston only recently granted the Cubs permission to speak with Epstein, but negotiations have already been completed between Chicago and the GM. The deal is expected to be finalized by the end of this week, once negotiations for compensation with the Red Sox have been finalized. Before coming to terms with the Cubs, Epstein was under contract for one more season with Boston.

It’s believed that Boston Red Sox assistant GM Ben Cherington will be the front runner to replace Epstein, but there could be some interest in Chicago White Sox assistant GM Rick Hahn.
