Florida has suspended seven players for its season opener against Michigan -- including its top playmaker, wide receiver Antonio Callaway -- for making improper charges on their student IDs at the school bookstore and then selling those items for cash, university officials confirmed to ESPN on Sunday.
One source said the cards did not have the proper amount of funds to purchase the items.
The other suspended players are offensive lineman Kadeem Telfort, linebackers James Houston and Ventrell Miller, and defensive linemen Jordan Smith, Richerd Desir-Jones and Keivonnis Davis.
Florida will face Michigan on Sept. 2 (3:30 p.m. ET on ABC) at AT&T Stadium in Arlington, Texas.
"We have a small group of players that have made some choices that are extremely disappointing," head coach Jim McElwain said in a statement, though he did not elaborate on the reason for the suspensions. "Action has been taken -- they have missed some practice and will miss the Michigan game. We will use this as a learning opportunity and we will have some players step up as we move forward."
Players are expected to either return the items or repay the bookstore. It's unknown if school officials will take further action.
This is not the first time Callaway has faced suspension during his time at Florida. He was suspended last spring amid sexual assault allegations. Callaway was accused of sexual assault in December 2015, but testified that he was "high on marijuana" during the incident and was "so stoned I had no interest in having sex with anyone."
Callaway was later cleared during his hearing in August 2016 and was reinstated to the team.
In May, Callaway was cited for misdemeanor marijuana possession after officers smelled marijuana in a vehicle driven by Kendrick Williams, 40. Callaway was a passenger in Williams' car and officers found 7 grams of marijuana in his pocket during a search. Williams also was found with marijuana.
Callaway and the driver claimed ownership of the drugs, but prosecutors dropped the charge as part of a July plea deal. Callaway was fined $301.
Callaway had 54 catches for a team-high 721 yards and three touchdowns last season.
Florida is ranked No. 16 in the coaches' preseason poll, and Michigan is ninth.
