The Cowboys signed cornerback LeQuan Lewis on Tuesday to fill the roster spot of released tight end Colin Cochart.
Coach Jason Garrett said the team targeted Lewis because of his strength on special teams.
Look for him to be active against the Seattle this weekend and be part of the coverage units trying to contain Seahawks dangerous returner Leon Washington.
Washington had a kickoff return of 83 yards and a punt return of 52 yards, leading to 10 points in the 20-16 loss to the Cardinals last week.
“You certainly want to limit his opportunities any way you can,” Garrett said. “The kickers and the punters play a big role in this game. There’s no question about that. But we have to go cover it. There’s no expectation that we can just take him out of the game by just kicking the ball through the end zone or whatever the case might be. We have to plan to practice really well in preparing for him, because again, he’s a difference-making player for their football team. We’ve got to get ready to cover well and certainly the kickers and the punters have a big job in this league in terms of how to kick the ball to give us favorable covering opportunities.”
