Terrance Williams 
is going to have to take a break from competing to be the Cowboys' No. 3 wide receiver. The rookie suffered a concussion during Friday's practice and has been ruled out for Sunday's Hall of Fame game against the Dolphins. According to Calvin Watkins of ESPN Dallas, Williams is already considered doubtful to play in Dallas' second preseason game, which takes place Aug. 9.
Fantasy Analysis:
The Cowboys considered Williams a first-round pick who fell into the third, but the Baylor product has been struggling with drops during OTAs and training camp. He and Dwayne Harris are vying for the No. 3 job, but I don't suspect either guy will have a lot of fantasy value without an injury to Miles Austin or Dez Bryant. Slot receiver Cole Beasley could also make the team and take some pressure off Dallas' top two wideouts.
