The Cowboys are moving on from one of their offensive playmakers following some off-field troubles. Dallas is releasing wide receiver Antonio Callaway after he was arrested last weekend in Miami for driving with a suspended license. The 26-year-old former fourth-round pick was signed to the practice squad late last season and never suited up for Dallas. In a corresponding move, the team signed wide receiver Tyron Johnson. Johnson has totaled 23 receptions for 422 yards and three touchdowns in 26 career games with four different teams.
