Williams (thigh) missed Thursday's practice.
Williams didn't suit up Week 8 due to a thigh issue, and even with the benefit of a bye he hasn't mixed into drills with just one session remaining during Week 10 prep. On a semi-positive note, he was seen running on a side field Wednesday, so the Lions may be exercising caution with the fifth-year pro. Friday's practice and ensuing injury report could be telling for Williams' ability to suit up Sunday in Pittsburgh. Behind top running back D'Andre Swift, the Lions have rookie Jermar Jefferson and Godwin Igwebuike at the position.
