Collins (groin) isn't participating in Wednesday's practice, Aaron Wilson of ProFootballNetwork.com reports.
According to Wilson, the Texans are viewing Collins as day-to-day ahead of Sunday's game against the Titans after he exited the team's Week 7 loss to the Raiders with the groin injury. If Collins is unable to overcome the groin issue in time for Sunday, Phillip Dorsett would likely pick up more reps alongside Brandin Cooks and Chris Moore in three-receiver sets.
