The Dallas Cowboys and Pittsburgh Steelers have begun their preparations for Week 5 in earnest. Wednesday marks the first official practice as the long-time rivals careen towards the next iteration of their series.

The Cowboys suffered numerous, serious injuries in their Week 4 win over the New York Giants. The Steelers have been dealing with major injuries throughout the season. It will make for interesting week of practice updates to see who will be able to make it to the game.

Already ruled out for the Cowboys is DeMarcus Lawrence, who the team placed on Injured Reserve on Monday. Micah Parsons and Brandin Cooks missed practice on Wednesday, as did two of the Steelers’ top three pass rushers. TJ Watt is fine, but Alex Highsmith is like Lawrence, already ruled out.

His backup, Nick Herbig, left Sunday’s loss to the Indianapolis Colts with an ankle injury and didn’t participate in Wednesday’s on-field work. Here’s a full list of who didn’t participate on Wednesday.
