Players can miss a significant amount of time with plantar fasciitis. Williams has been trying to practice and play through the pain, but it's starting to hinder his performance.
"As a defensive lineman, I count on my feet," Williams said. "(It impacts) everything I do, like pushing off, changing directions, turning a corner. To have one foot, you can think about what it is like."
Williams will be monitored closely in the upcoming weeks. Regardless of his status, the Texans likely will have to scour the waiver wire for defensive linemen.
Defensive end Antwan Peek is expected to miss time with a sprained medial collateral ligament, and defensive tackle Lional Dalton is already on the inactive list with a twisted ankle.
Among others injured: outside linebacker Shantee Orr (ankle), safety Glenn Earl (dislocated middle finger), safety Jason Simmons (quadriceps contusion) and cornerback Lewis Sanders (broken hand).
