Coach Jim McElwain made the announcement after practice Wednesday, saying Grier ''played pretty good in some situations last week'' and ''deserves to go this week.''
After splitting snaps with sophomore Treon Harris in the first two games, Grier has gone the distance in the last two. He was at his best down the stretch against Tennessee last week, hitting 11 of his final 18 passes for 149 yards and two touchdowns.
Grier has thrown for 725 yards and six touchdowns this season. He also has two rushing scores and four turnovers, including three interceptions.
McElwain says Harris also had a good week of practice, adding ''both guys are ready to go.''
