Arizona got involved late in the process and looked to have an inside edge when his good friend Kaniela Tuipulotu gave a commitment to the Wildcats.
That was not enough to sway Fotu, who decided along with his family to stick with Utah.
Rumors swirled Wednesday morning that Fotu had planned on signing with Arizona, but those proved to be false.
"I had heard this morning that it was going to be Arizona," Beirne said. "He really wanted to honor that original commitment."
