The Boston Red Sox were unable to reach an agreement with general manager Theo Epstein on Friday and negotiations on a new contract are expected to go on until Monday, when his current deal expires. ``Talks continue,'' owner John Henry said in an e-mail. The Red Sox do not like to announce deals on weekends, especially with the New England Patriots playing Sunday night and linebacker Tedy Bruschi expected to make an emotional return from a stroke. ``We're not expecting any news today,'' Red Sox spokesman Glenn Geffner said. ``I wouldn't imagine we'll have an announcement over the weekend.'' Epstein reportedly rejected a three-year deal worth $1.2 million annually, triple his previous salary. The youngest general manager to build a World Series-winner, he was reported to be seeking something closer to the $2.5 million a year the Red Sox offered Oakland Athletics GM Billy Beane before Epstein was hired.
