ESPN reported the extension runs through 2015, per the Detroit Free Press.
That means Schwartz isn't going anywhere, to the dismay of some Lions fans.
Some believe Schwartz should be on the hot seat after the Lions followed their first playoff appearance in 12 years a season ago with a 4-11 record. But Schwartz has brought the Lions back to relevance after the 0-16 season in 2008. And the Ford family is extremely loyal -- some say to a fault. Matt Millen lasted eight years as a general manager in Detroit with a 31-97 record and no winning seasons.
Schwartz will coach the Lions through the 2013 season, at least.
