The Houston Texans have placed wide receiver Nico Collins on injured reserve due to a hamstring injury, which will keep him sidelined for at least the next four games. Collins, who currently leads the NFL with 567 receiving yards this season, sustained the injury during a game against the Buffalo Bills in Week 5. Coach DeMeco Ryans initially described the injury as 'week-to-week' before the decision to place him on IR was made.
