IRVING, Texas -

The Dallas Cowboys have waived quarterback Dalton Williams and offensive tackle J.B. Shugarts, creating more roster space four days before their first training camp practice.
    
The move Wednesday on Williams, a rookie free agent from Akron, leaves Dallas with three quarterbacks in Tony Romo, Kyle Orton and Nick Stephens.
    
Shugarts is a second-year player out of Ohio State.
    
The Cowboys have three open spots on their 90-man camp roster after last week's release of fullback Lawrence Vickers.
