Duke associate head coach Steve Wojciechowski has reached an agreement in principle to become the next head coach at Marquette, a source told CBSSports.com on Tuesday.

A formal announcement is expected soon.

CBSSports.com previously reported that Wojciechowski interviewed with Marquette early Monday about replacing Buzz Williams, and the 37-year-old former McDonald's All-American became the front-runner late Monday when CBSSports.com reported that Tennessee's Cuonzo Martin had removed his name from consideration. This development means Duke coach and Hall of Famer Mike Krzyzewski, college basketball's all-time winningest coach, now has 12 former players or assistants who have become Division I head coaches.

Williams left Marquette on March 21.

He's now the head coach at Virginia Tech.
