"I have no idea who it is," Holgorsen said. "I don't know his name. I don't know where he's from. I don't know if he can throw left handed or right handed. I don't know anything."
Loy wore a helmet in practice and stood by the quarterbacks throughout, but he did not have pads on, as he is not allowed to wear pads in his first two days of practice, according to NCAA rules.
Loy, a 6-foot-1, 168-pound Fort Ashby, W.Va. native, was a three-year letterwinner and two-year starter at Frankfort High School. Loy transferred to WVU from Potomac State Junior College in 2009 and left the football program after that season.
Holgorsen has said he would like to have five quarterbacks on the roster, meaning the team's walk-on tryouts later this month are still of significance.
"If you've got leads on two or three more, we need them," Holgorsen said. "We need as many arms as we can get."
"That list is going to grow," Holgorsen said.
"He didn't reinjure his shoulder, but he tweaked something," Holgorsen said.
"He was calm, and he was communicating better," he said. "We were probably pressing on him too much for a few days, but the good news is that we didn't make that mistake two games into the season."
The first-year head coach said it has been a challenge to slow down Smith during camp to help install the offense. On Thursday, the offense ran at a slower pace, and Holgorsen felt Smith was at his best.
