Quarterback Kyle Gallup, who played for Marshall in 2015, is joining the University of Hawaii football team this summer.

Gallup might be eligible to compete this coming season because he was not on scholarship at Marshall and he will join UH as a walk-on. The NCAA usually requires a Division I player to sit out a season after transferring, but there is an exemption for a transfer involving a walk-on.

Gallup, who is 6 feet 2 and 215 pounds, redshirted as a freshman in 2015.

Gallup said his decision is partially family-related. His mother was diagnosed with a muscular condition that is aggravated by cold weather. She is pondering a move from Colorado, where Gallup was raised, to Hawaii. Gallup said the family is hopeful that relocating from the cold climate “can fix her condition or, at least, help it.”

Gallup said he enjoyed his time at West Virginia-based Marshall. The Thundering Herd defeated Connecticut, 16-10, to win the 2015 St. Petersburg Bowl and clinch a third consecutive 10-victory season.

“It was a good time for me,” Gallup said. “But as far as playing, it would be better if I went somewhere else. Then when everything happened with my mom, it was better to be closer to home.”

Ikaika Woolsey, Beau Reilly and Aaron Zwahlen were the only scholarship quarterbacks who participated in spring training. Walk-on quarterbacks Hunter Hughes and Toagamalu Brown also were on the spring roster. Cole McDonald, who signed in February, joins next month.

Gallup had received widespread interest before suffering a season-ending injury in the first game of his high school junior year in 2013. As a Chaparral High senior, Gallup completed 66.4 percent of his passes for 1,850 yards and 20 touchdowns in nine games. He also earned the nickname “Tebow” because of his admiration of the 2007 Heisman Trophy winner.

Chaparral and Marshall both ran spread offenses in which the quarterback was mostly in the shotgun. The Rainbow Warriors employ elements of the spread attack in their new hybrid offense.

Gallup is familiar with Nick Rolovich, UH’s first-year head coach and a former Warrior quarterback.

“My dad’s really good friends with (John) Elway,” Gallup said of the Hall of Fame quarterback who now is the Denver Broncos’ executive vice president. “Rolo played with Denver (in training camp) back in the day. John knew about him.”

The Gallup poll on Rolovich? “He’s a very personable person,” Gallup said. “He connects well with the players. I think I’m going to enjoy that.”
