McKenzie, 5-foot-11 and 225 pounds, will be a senior this year for the T-Birds and recently ran a time of 4.6 seconds in the 40-yard dash at a USC camp. He is ranked 70th nationally by Scout.com at his position.
On Saturday, McKenzie traveled to Seattle to attend a camp at the University of Washington, followed by camps at Oregon and Oregon State.
In the middle of last week, BYU offensive coordinator Robert Anae asked McKenzie if he'd spoken to any of BYU's coaches. Anae told McKenzie that BYU had too many running backs and would help find him a place at Arizona or Arizona State.
"This surprised my son, who contacted coach Brandon Doman, who confirmed the scholarship had been withdrawn," his father, Bert, said.
The withdrawal stunned and angered Bert. "If I've lost sleep over this, I can just imagine what my son is feeling."
