This was a roller coaster afternoon for those who follow both Michigan and Stanford football. It began when a report from the Ann Arbor media indicated that Wolverines coach Jim Harbaugh had successfully lured respected Stanford sports performance director Shannon Turley to Michigan.

But a few hours later, the tide turned: Multiple sources have confirmed to ESPN.com that Turley is not headed to rejoin his former boss at Michigan. He will remain at Stanford.

This is excellent news for the Cardinal and a disappointing development for the Wolverines, to say the least. Turley's innovative strength and conditioning program has turned Stanford into a physical force while curbing the program's injury rate. Since Turley joined the Cardinal program, the team has seen an 87 percent decline in games missed due to injury. Stanford team doctors, coaches, and players have credited Turley's avant-garde focus on "functional strength" -- which includes integration of Pilates into the Cardinal's regular routine -- for much of the program's health and success.

In 2013, Turley's position became the first endowed sports performance directorship in collegiate athletics -- a surefire sign of his value to the Stanford program.

Turley is not the only Stanford assistant to have drawn reported interest from Harbaugh, who coached the Cardinal from 2007-10 and is currently assembling his new coaching staff in Ann Arbor. Fox Sports' Bruce Feldman has tweeted that Michigan is currently pursuing Stanford recruiting/defensive coordinator Lance Anderson.
