Right tackle La'el Collins proved his physical and mental toughness and impressed the Dallas Cowboys with a bulging disc in the 38-14 victory against the Washington Redskins last week after not practicing all week. Collins is not expected to practice Wednesday and could be held of practice again this week. But he expects to play against the New York Giants Sunday. Last week was the first time Collins played in a game after not practicing. “It’s something I’ve been dealing with, a little injury,” Collins said. “Sometimes it has to go that way. Sometimes you can’t get out there physically during the week but you know you have to be ready to go for the game.
