The Dallas Cowboys have placed defensive end DeMarcus Lawrence on injured reserve due to a Lisfranc injury in his right foot. Lawrence is expected to be out for 4-8 weeks but will not require surgery. In response, the Cowboys have signed K.J. Henry from the Bengals' practice squad and are likely to elevate Carl Lawson for their upcoming game against the Steelers. The team is also preparing to play without Micah Parsons, who is dealing with a high ankle sprain.

• DeMarcus Lawrence's injury significantly impacts the Cowboys' defensive line.
• K.J. Henry's signing indicates the Cowboys' need for depth at defensive end.
• Micah Parsons' absence adds to the Cowboys' defensive challenges.
