IRVING, Texas -- With Tyron Smith’s status for Sunday’s game at the New York Jets uncertain because of a hyperextended knee the Cowboys are looking at all of their contingency plans.
If Smith cannot play, Jermey Parnell would start, which would leave the Cowboys without a true backup tackle. Having cut Sam Young, the Cowboys have only three offensive tackles on the 53-man roster, so Jason Garrett has had Derrick Dockery, Kyle Kosier and rookie David Arkin get some work at tackle this week.
Kosier played a couple of games at tackle in San Francisco in 2003. Dockery, who has 111 career starts in eight seasons at guard, was signed Monday. Arkin played left tackle at Missouri State last year.
“I did a little bit of it my rookie year in training camp and then I was moved over at guard, so it’s been since college,” Dockery said, adding that the coaches, “told me to be ready for whatever. I’m going into my ninth year so I played with some great players. If need be, it’s going to be different, but I’m going to fly around and play hard.”
