ST. PETERSBURG, Fla. — Crowder met the "teen" online and during the course of several conversations sent four sexually explicit photographs to her, deputies said.
He then arranged to meet with her to "engage in sexual acts with him," the Sheriff's Office said in a release.
The arrest came as part of the Sheriff's Office "Operation Wayfarer," which targets adult males who are seeking out underage females on the internet for the purpose of engaging them in sexual activity.
The Sheriff's Office did not release any information on the age or gender of the person in "Operation Wayfarer" that Crowder was actually corresponding with.
Crowder said he knew the girl was 14 and admitted to sending the photographs, investigators said.
He was charged with certain use of computer services prohibited and four counts of transmission of material harmful to a minor.
All five charges are felonies.
The University of Tennessee website lists Crowder, of Bristol, Tennessee, as a senior guard and center last season.
