Scott Shafer will be the next head coach at Syracuse, a source told CBSSports.com Monday night.

The 46-year-old Shafer was named Syracuse’s defensive coordinator in 2009, and his 2010 unit ranked among the best in the Big East, allowing just 19.3 points and 300.3 yards per game. Under Shafer, the Orange defense ranked sixth nationally and led the BIG EAST in tackles for loss in 2012.

Shafer replaces Doug Marrone who was hired over the weekend as the new coach of the Buffalo Bills.
