The Boston Bruins and Boston Garden are being sold to a Boston group headed by investor James F. Brennan and real estate broker Godfrey Wood for $50 million, Delaware North Inc., the current owners, said yesterday.

The agreement in principle to purchase the National Hockey League team and the arena was announced in Buffalo by Delaware North Chairman Jeremy M. Jacobs and Brennan.

The deal will be completed within two weeks, they said in a news release.

The deal ends a five-day contest for ownership of the NHL team and the aging Garden. Also bidding was a group led by Bruins President Paul Mooney and including Celtics basketball owners Don F. Gaston and Alan Cohen.

Estranged defenseman Chris Kotsopoulos returned to the Hartford Whalers' training camp to find he had worn out his welcome.

Chief executive Emile Francis told the four-year veteran his suspension, imposed Monday when he missed practice and refused to play in a rookie scrimmage against the New York Islanders, was lifted -- but the Whalers did not want him practicing while they try to trade him.

Kotsopoulos took the club to arbitration over salary and the case was heard Tuesday night, decision pending . . .

Todd Bergen, a rookie center who scored 11 goals in just 14 NHL games last season -- plus four in the playoffs -- has told the Philadelphia Flyers he won't be back this year. He wants to pursue, he said, an education and a career in professional golf.
