FORT WORTH, Texas (AP) - The last of four former TCU football players arrested in a drug sting earlier this year has pleaded guilty to marijuana delivery charges and received probation.

The four were among who were among more than a dozen students netted by the sting.

Tarrant County district attorney's spokeswoman Melody McDonald said Thursday that Devin Johnson entered his plea in August and also was ordered to pay a $300 fine and court costs.

Former players D.J. Yendrey, Tanner Brock and Tyler Horn pleaded guilty a few weeks before Johnson and received similar sentences.

The arrests came in February after a six-month drug investigation by Fort Worth police acting on a tip that a player was selling marijuana to other players and students.
