Adding to the intrigue of this news is that Dykes will be coaching against Louisiana Tech, a school he coached at from from 2010 to 2012. He spent four years at Cal, where he had just one winning season.
Dykes is a native of Big Spring, Texas, and his Texas ties should serve him well on The Hilltop.
Dykes will replace Chad Morris, who left SMU last week to become Arkansas' coach.
Dykes started coaching wide receivers at Texas Tech in 2000, and he left Lubbock in 2006 after serving two years as the Red Raiders' co-offensive coordinator.
SMU interim coach Jeff Traylor was supposed to coach the Mustangs in the Frisco Bowl, but is following his former boss to the Razorbacks.
Dykes spent this season with the Horned Frogs as an analyst, a non-coaching and non-recruiting position, helping evaluate the offense and prepare game plans.
A press conference is scheduled for 11 a.m. Tuesday at SMU.
Multiple reports say that SMU football's next head coach will be Sonny Dykes. "I don't think anything is going to change in that regard".
The TCU assistant coach is the favorite for the job.. "I have an opportunity to come back to Texas where I grew up". "My dad was a college football coach and a high school football coach, and we moved around a lot".
"Gary [Paterson] has been a friend of mine through the years", Dykes said.
Dykes oversaw the maturation of Jared Goff from wide-eyed freshman to No. 2 overall pick in the 2016 NFL Draft.
Dykes said being at SMU feels like "coming home".
