Even though week 3 of the NFL preseason is dubbed as a dress rehearsal for the regular season, the Dallas Cowboys have decided to rest quarterback Dak Prescott and running back Ezekiel Elliott for Sunday night's games against the Arizona Cardinals.
The decision is likely based on the current health of the offensive line. Tyron Smith (hamstring), Zack Martin (knee), and La'el Collins (calf contusion) are all battling injuries.
Center Travis Frederick is out indefinitely after being diagnosed with Guillain-Barre Syndrome earlier in the week. Backup Joe Looney has been taking first-team snaps in practice.
