The Texans placed Whittington (quadriceps) on the practice squad injured list Thursday, Jonathan M. Alexander of the Houston Chronicle reports.
Whittington suffered a torn quad during practice this week, and while the move to the injured list will prevent him from being eligible for elevation for four weeks, the rookie could be sidelined for longer. Whittington linked up with Houston as an undrafted free agent in early May following a strong senior season with Oregon.
