OXNARD, Calif. -- Cowboys rookie wide receiver Terrance Williams left Friday's practice and was being tested for a possible concussion.
If Williams, who collided with cornerback Brandon Underwood during a passing drill, fails the baseline test, he will miss the Hall of Fame game against the Miami Dolphins on Sunday. Williams has to be symptom-free for a certain amount of days before being cleared to play. The Cowboys' second preseason game arrives quickly -- Friday, Aug. 9 at Oakland -- and he could miss that game as well.
*Kevin Kowalski (knee surgery), Ryan Cook (back), Ray Dominguez (shoulder), Nate Livings (knee surgery), Demetress Bell (conditioning), Jermey Parnell (hamstring), Alex Albright (back), Jay Ratliff (hamstring) and Anthony Spencer (knee surgery) missed practice and won't play in the Hall of Fame game.
