NEW HAVEN, Conn. — Yale football coach Jack Siedlecki has announced that he is retiring after 12 years and two Ivy League championships, but he'll be staying at the university to become assistant director of athletics.

Siedlecki was 70-47 and 47-37 in the conference during his tenure in New Haven, which included sharing league championships with Brown in 1999 and Princeton in 2006.

The Bulldogs were 9-0 heading into last year's final game and looking for their first perfect season since 1960, but lost to Harvard. Yale finished this season 6-4, including 4-3 in the conference.

Siedlecki took the helm after Hall of Famer Carm Cozza retired in 1996 after 32 seasons.
