Stafford (thumb) doesn't have an injury designation for Thursday's game against the Texans, Tim Twentyman of the Lions' official site reports.
Stafford upgraded to a full practice participation Wednesday after beginning the week with back-to-back limited sessions. The 32-year-old played through a torn ligament in his right thumb during last weekend's loss to the Panthers, which may have contributed to him passing for a season-low 178 yards and no touchdowns in a game the Lions were trailing throughout. Stafford will look to put his injury fully behind him versus the Texans, though he'll have to accomplish that task without two of his top weapons in the passing game in Kenny Golladay (hip) and Danny Amendola (hip).
