Cowboys News: Tyron Smith Among 3 OL Questionable vs. Cardinals with Injuries

The injury bug continues to be an issue for the Dallas Cowboys amid a fantastic start to the season.

Three of the team's top offensive linemen have been placed on the injury report ahead of Sunday's game against the Arizona Cardinals. Left tackle Tyron Smith was added to the report Saturday with a hamstring injury, according to ESPN's Todd Archer.

Smith joins guard Zack Martin (ankle) and center Tyler Biadasz (hamstring), who are also listed as questionable.

With Smith being such a recent addition, it's unclear what the severity of the injury is and whether or not it'll keep him out of action Sunday. Smith has had an extensive injury history over his career, most recently playing only four games last season after tearing his hamstring in training camp.

There does seem to be a bit more optimism with the other two linemen.

While speaking with 105.3FM The Fan, coach Mike McCarthy felt confident about Biadasz's availability following an MRI on his hamstring.

"Talking with the medical staff last night, they think he'll be ready to go,'' McCarthy said. "But when you have these type of things show up late like they do, the next morning is obviously an important evaluation. But they were not of high concern last night."

As for Martin, who dinged up his ankle during Dallas' victory over the New York Jets last week and exited early, it's still not 100 percent clear whether he'll play. He practiced on the side throughout the week.

However, Martin did previously say he felt he could've kept playing against the Jets.
