JERSEY CITY, N.J. — Peter Chiarelli once considered Milan Lucic, David Krejci, and Nathan Horton the best line in hockey.

On Saturday, the Bruins general manager learned it will not remain intact in 2013-14.

Nathan Horton’s camp informed the Bruins he will not re-sign with the club prior to Friday, when free agency opens. The first-line right wing will be one of the prime targets on the open market. This will be Horton’s first opportunity to become an unrestricted free agent.

Horton is coming off a six-year, $24 million contract, and could command a $6 million annual payday from another club.

The Bruins considered re-signing Horton among their first orders of business prior to Friday. Horton appeared in 169 regular-season games for the Bruins over the last three years. Full story for BostonGlobe.com subscribers.
