FRISCO, Texas _ Dez Bryant sustained a concussion during practice Monday, and will not play in the Dallas Cowboys' preseason game at the Seattle Seahawks on Thursday.
Defensive tackle Tyrone Crawford has also been ruled out because of a concussion, a team spokesman said. It's unknown at this time whether Bryant or Crawford will make the trip with the team.
The third preseason game is known as the "dress rehearsal," the game in which the regular starters see their most action before the regular season.
Bryant has four catches for 74 yards and two touchdowns in two preseason games so far. He caught a TD in each of them. Bryant, who underwent offseason foot surgery, sat out only one practice during training camp.
Crawford, meanwhile, recorded his first sack of the preseason last Friday against the Dolphins. He sustained a concussion during Sunday's practice.
