Four of the Cowboys’ five starting offensive linemen are dealing with injuries.
Left tackle Tyron Smith missed the last two days of practice while nursing a sore hamstring and right tackle La’el Collins was out Friday with a calf contusion and an illness.
Right guard Zack Martin is out until the start of the regular season with a hyper-extended knee and center Travis Frederick is out indefinitely with Guillain-Barre syndrome.
If there was ever any question about quarterback Dak Prescott and running back Ezekiel Elliott playing in Sunday’s preseason game against the Arizona Cardinals then that answers it.
