"Will came to me about exploring his options to transfer. We will support him and help him in anyway we can," coach Jim McElwain said in a statement. "This has been very difficult on him and obviously he is looking for a fresh start. We will always be there for him as will all Gators."
Grier, a redshirt freshman, was suspended Oct. 12 after testing positive for performance-enhancing drugs and lost the appeal of his one-year suspension in November. He would not have been eligible to return until Florida's seventh game of the 2016 season, against Missouri on Oct. 15.
Until his suspension, Grier had been a breath of fresh air for Florida. He became the first Gators quarterback since Tim Tebow in 2009 to pass for more than 200 yards in three consecutive games. Grier's completion percentage, passing yards per game and touchdown-to-interception ratio also were the best by a Gator since 2009.
In all, Grier played in six games this season, starting five of them, and completed 66 percent of his passes for 1,204 yards with 10 touchdowns and three interceptions.
