Cowboys defensive end DeMarcus Lawrence missed practice Wednesday due to a foot injury. Lawrence was the only non-participant in practice as Dallas gears up for a matchup with the Minnesota Vikings this Sunday. The group of linebacker Anthony Barr, running back Ezekiel Elliott, and cornerback Anthony Brown were all limited to start the week. In other news, the Cowboys signed former 2017 first-round pick Takk McKinley to the practice squad. McKinley has 20 career sacks.
