Grier was suspended for one year in the middle of last season for testing positive for performance-enhancing drugs. The suspension would have sidelined him for about half of this season, but he decided to transfer out of Florida. That move will require him to sit out the entire 2016 season. It was unclear whether the suspension would carry over to 2017.
On Friday, Holgorsen said in a statement that Grier is enrolled at West Virginia, but he could not officially confirm his eligibility until the summer of 2017.
"However, I fully anticipate him being eligible for the opening game of the 2017 season," Holgorsen said.
Grier appealed his one-year suspension, but the NCAA upheld its ruling. He played in six games last season as a redshirt freshman, starting five, and completed 66 percent of his passes for 1,204 yards, with 10 touchdowns and three interceptions.
