The Arizona Cardinals will have at least two vacancies to fill on their defensive staff. A day after they lost linebackers coach Sam Siefkes, who became the defensive coordinator at Virginia Tech, they will need to find a new defensive line coach.

Sam Siefkes also is a former Wofford and Wisconsin-Platteville defensive coordinator, and he worked as a quality control coach for the Minnesota Vikings.

Virginia Tech has hired Sam Siefkes as defensive coordinator after he spent the last two seasons as the Arizona Cardinals’ linebackers coach.
