The Dallas Cowboys signed K.J. Henry off the Cincinnati Bengals' practice squad on Tuesday after placing fellow defensive end DeMarcus Lawrence on injured reserve. Lawrence sustained a Lisfranc injury to his right foot in the third quarter of last Thursday's 20-15 road win against the New York Giants. The four-time Pro Bowl selection is not expected to have surgery but will need four to eight weeks to recover. Lawrence, 32, has three sacks and 14 tackles in 14 starts this season. He has 61.5 sacks, 21 forced fumbles, eight fumble recoveries and two interceptions in 141 games (123 starts) since Dallas drafted him in the second round in 2014.
