Detroit Lions vs. Dallas Cowboys Week 4 injury report: Frank Ragnow limited with knee injury If there was any hope that Wednesday was just a rest day for Ezekiel Ansah to get him ready for Sunday’s game against the Dallas Cowboys Barry Sanders Jersey , that was shut down on Thursday. The Lions’ pass rusher was absent for the second straight day as he continues to rehab from a shoulder injury suffered in the first half of the Detroit Lions’ Week 1 game against the New York Jets.Now having missed back-to-back practices, it seems unlikely that Ansah will be available to play against the Cowboys, leaving the Lions shorthanded on the edges yet again. Of course, last week against the Patriots, the Lions only rolled with two “defensive ends,” Romeo Okwara and Da’Shawn Hand, choosing to scratch Kerry Hyder, despite being healthy. The Lions’ pass rush would undoubtedly be improved with a healthy Ansah Michael Roberts Jersey , but it hasn’t been impotent without him. Detroit currently has 10 sacks, tied for the fourth most in the league. Perhaps more concerning is the new injury to Lions left guard Frank Ragnow. The rookie offensive lineman popped up on the injury report with a knee injury. He still practiced but in a limited fashion. Ragnow is coming off his best game as a professional, helping open up lanes for Kerryon Johnson to become the Lions’ first 100-yard rusher in five years. If he can’t go Sunday, the Lions would likely turn to Kenny Wiggins or Joe Dahl. Remember, starting right guard T.J. Lang is still battling through a back injury, but he played in every snap last week. In addition to Ansah and Ragnow, tight end Michael Roberts also missed his second straight practice after suffering a knee injury late last week. It’s an unfortunate development after Roberts earned his first NFL touchdown in Week 2.
