The Cardinals placed Lawrence (calf) on injured reserve Saturday, Darren Urban of the Cardinals' official site reports. Lawrence was already ruled out for this Monday's game versus the Cowboys, and now he won't be eligible to return until Week 9 against the Bills. However, the rookie fourth-rounder doesn't have a clear timeline to return. Corey Peters will continue starting at nose tackle, and Angelo Blackson or Leki Fotu may need to slide over from defensive end to add depth behind Peters.
Lawrence suffered a calf injury during Sunday's win over the Jets, Darren Urban of the Cardinals' official site reports. The rookie fourth-rounder out of LSU has maintained a consistent role on defense, operating as the No. 2 nose tackle behind Corey Peters. He's in danger of missing time due to the soft-tissue nature of his injury, but Thursday's practice status should reveal more about the severity of his issue.
