Florida redshirt freshman quarterback Will Grier has been suspended for the rest of the season after failing an NCAA drug test, but the Gators plan to appeal the suspension, UF coach Jim McElwain said.

The news comes on the Monday ahead of the highly anticipated meeting between No. 6 LSU (5-0, 3-0 SEC) and No. 8 Florida (6-0, 4-0) on Saturday night in Tiger Stadium. It was first reported by gridironnow.com.

Grier, a Davidson, North Carolina, native, has completed 106 passes in 161 attempts (65.8 percent) with 1,204 yards and 10 touchdowns. He’s thrown just three interceptions. Grier, a once highly touted rookie out of high school, took over for sophomore Treon Harris as the starter in the second game of the season.

Grier is Florida’s second leading rusher at 116 yards. Harris, a dual-threat QB from Miami who is expected to start, is 19 of 27 for 269 yards and two touchdowns. He’s played in four of the Gators’ six games.

Harris had usurped Jeff Driskel as the Gators quarterback last season, but he was suspended amid an NCAA investigation for sexual assault.

ESPN.com and The AP reported that Grier tested positive for performance-enhancing drugs.

LSU coach Les Miles was made aware of the Grier news just before his weekly press conference on Monday.

“Coach (Jim) McElwain will have them ready to play,” Miles said. “Most of the time, second team quarterback can operate the offense as is. We expect the core plays are the same. Very capable running back. Would suggest passing be the same.”

Miles’ team is used to playing a backup quarterback. For a fourth straight game, LSU will play a team’s backup or No. 3 quarterback.

“We’ll show up. We’ll be there,” McElwain said at a press conference on Monday.

Grier revealed during the press conference that he took a supplement from GNC that included a banned substance.
