Defensive end Demone Harris is being signed to the Texans' active roster from the practice squad, per a league source. The Texans placed veteran defensive end Mario Addison on injured reserve with a groin injury. The Texans also signed veteran linebacker Kevin Pierre-Louis to the active roster from the practice squad and elevated quarterback Jeff Driskel and wide receiver Chris Conley to the active roster from the practice squad.
The Texans already signed former Tennessee Titans outside linebacker-defensive end Derick Roberson to the practice squad with veteran defensive ends Rasheem Green (thigh) and Addison sidelined at practice. Addison was listed as doubtful on the injury report, and Green is questionable for Sunday's game against the Indianapolis Colts at NRG Stadium.
