Bradshaw, 22, is serving a sentence at the Southwest Virginia Regional Jail.
A spokesman for the jail told PA SportsTicker that said Bradshaw voluntarily checked himself into the facility Sunday. He also said Bradshaw will “serve a certain amount of time.”
Bradshaw was sentenced to two years probation in 2006 for a misdemeanor petty larceny charge while attending Marshall University. He was charged with stealing a PlayStation game from another student.
As a rookie last season, Bradshaw played in 12 games for the Super Bowl champion Giants, rushing for 190 yards and a touchdown on 23 carries.
