McDonald's All-American forward Chris Walker did not academically qualify to enroll at the University of Florida and has until December to become eligible.

The school’s drop/add period for fall classes ended Tuesday. If Walker does qualify, he would be eligible beginning with a Dec. 17 matchup with Memphis.

The 6-foot-11 Walker, a native of Bonifay, is ranked the nation’s No. 12 recruit by ESPN.

"Now I understand how serious high school is and that you can't take the work lightly," Walker told's Jeff Goodman on Tuesday. "I didn't do as well and work as hard as I should have early in high school.

"It's a minor setback, and every day I'm working hard to get to Florida. My plan is to definitely be at Florida. I'm working every day to make sure I get to Gainesville."

Walker is an explosive shotblocker and finisher who chose Florida over over Kansas, Connecticut, Baylor and Florida State. He had 39 points, 26 rebounds and six blocked shots in a game last season.

Walker was expected to help give Florida impressive depth in the frontcourt this season. The Gators return seniors Patric Young, Will Yeguete and Casey Prather from an Elite Eight team, while adding forwards Damontre Harris from South Carolina and Dorian Finney-Smith from Virginia Tech.

Walker's ineligibility answers one of the looming offseason questions facing coach Billy Donovan's programs.

Senior point guard Scottie Wilbekin remains suspended from the team, while the NCAA has yet to decide whether Rutgers transfer Eli Carter will be eligible.
