The Bruins announced that defenseman Matt Bartkowski has decided to relinquish his two years of remaining NCAA eligibility and sign an entry-level deal with the club.

Bartkowski, 21, was acquired at the trade deadline from Florida as part of the deal that brought Dennis Seidenberg to Boston. As a sophomore at Ohio State, the former Panthers seventh-round pick skated in 39 games and posted 6-12-18 totals.

Last month, Bartkowski told The Bruins Blog he was 90 percent certain to stay in school. But obviously the uncertainty of the coaching situation at OSU, combined with the riches of a pro career, outweighed sticking around to get his engineering degree.

“Obviously, he wanted to leave,” Bruins general manager Peter Chiarelli said. “I met with the parents in Pittsburgh a month or so ago.”

“He’s a two-way defenseman,” Chiarelli continued. “He’ll need some time in the minors. He’s a good skater, he pushes the puck pretty well, has an element of grit, toughness, good size. So he’ll need to get accustomed to the pro game and see where it goes.”
