Texans LB Kamu Grugier-Hill left Sunday's game on a cart after suffering a right knee injury in the loss to the Seahawks. Aaron Wilson of the Houston Chronicle reports that early tests reveal a sprain, though, rather than a more severe injury as initially feared. That would likely mean further missed time for Grugier-Hill but isn't believed to be season-ending. We'll see about his official return timeline. LB Neville Hewitt saw elevated playing time in Grugier-Hill's absence and figures to start in his place going forward. The team, of course, waived LB Zach Cunningham, who is now with the Titans.
