Dallas Cowboys first-round pick Tyler Guyton suffered a suspected ACL tear during Monday's practice. While he walked off the field under his own power, initial fears indicate a serious knee injury. An MRI is scheduled to confirm the diagnosis. Guyton's injury leaves the Cowboys with a significant hole at left tackle, forcing them to consider shifting Pro Bowler Tyler Smith from left guard or relying on less experienced backups.
