Tony Robinson, former University of Tennessee quarterback, is in solitary confinement at the Knox County Penal Farm in Knoxville, Tenn., for violating work privileges, said Bill Russell, prison superintendent.

Robinson, who played for the Washington Redskins’ replacement team during the NFL strike last fall, has only a month to go before his scheduled release from jail on cocaine possession charges.

Russell said Robinson, who turned 24 Friday, was on a 50-prisoner work detail at Hillcrest Nursing Home when he left without permission sometime after 8:30 a.m Friday.
