Former University of Georgia football coach Jim Donnan told a judge he won't testify in his trial on federal charges including conspiracy, mail fraud and wire fraud.

The prosecution rested its case around midday Tuesday and the defense began calling witnesses. The defense finished with all but one in about two hours, with one left to go Wednesday morning.

The judge told jurors they will likely begin deliberations Wednesday after lawyers for both sides give their closing arguments.

Prosecutors say the 69-year-old and another man ran a fraudulent investment scheme through a West Virginia-based company dealing in wholesale and closeout merchandise.

Prosecutors say Donnan used his personal and professional relationships to lure investors. If convicted, Donnan faces a potentially lengthy prison sentence.
