Dunkley, 21, was arrested on USF's campus late Saturday night by Hillsborough County sheriff's deputies hours after USF's 30-17 loss to Florida State. Dunkley's charge, a first-degree misdemeanor, stemmed from an incident that occurred with his girlfriend on Sept. 21, according to a Hillsborough County arrest report.
"Our players have an obligation to conduct themselves in an appropriate manner on and off the field," coach Skip Holtz said in a statement. "Due to the serious nature of this matter, we have suspended Chris indefinitely from all team activities."
The arrest report indicates Dunkley "forced the victim to the floor and began to punch and strike the victim in the arms and legs causing bruising." Then Dunkley "grabbed the victim's hair and forced her into a closet where he began to strike the victim with a computer cord on the back of the thighs, causing several lacerations."
The report also indicated there is "a strong likelihood of repeat violence" by Dunkley.
In 2010, Dunkley transferred to USF from Florida. This season as a sophomore, he had four catches for 93 yards, including one catch for 10 yards against FSU on Saturday.
