Detroit, MI (SportsNetwork.com) - The Detroit Tigers have scheduled a press conference for Monday morning and a report indicates that Jim Leyland won't return as the club's manager.

According to Fox Sports, Leyland informed the team of his decision after the Tigers lost to the Boston Red Sox in the American League Championship Series.

Leyland spent the past eight seasons with the Tigers, guiding the club to four playoff appearances and two American League pennants. Detroit reached the World Series in his first season of 2006, falling to the Cardinals, and also lost to the Giants in last year's Fall Classic.

The Tigers were 93-69 this past season and won the American League Central title for the third straight year. Leyland posted a mark of 700-597 during his eight-year tenure in Detroit.

Now 68 years old, Leyland also managed the Pirates for 11 seasons, the Marlins for two years and the Rockies for one. He has a career record of 1,769-1,728 and was named Manager of the Year three times.

Leyland led Pittsburgh to three straight NL East titles from 1990-92 and left after the 1996 season to become the skipper with the Marlins. He guided the Marlins to their first World Series title in 1997 and spent one more season in Florida before taking over in Colorado in 1999. After a six-year hiatus, the Tigers hired him in 2006.
