Van Noy noticed the injury Thursday and sat out Friday's preseason game against the Jacksonville Jaguars. He told reporters after Saturday's practice that he fears his injury may be a sports hernia, but will undergo more testing this week to determine its exact nature and how long it will keep Van Noy out.
The Lions selected Van Noy in the second round of this year's draft. He is currently competing for the starting job at one of Detroit's two outside linebacker spots.
