Collins (calf) didn't participate in practice Thursday, Aaron Wilson of KPRC 2 Houston reports.
Collins was a limited participant Wednesday, so the wideout's absence a day later makes Friday's session a pivotal one in terms of deciding his status for Sunday's game against the Bengals. On the plus side from the Texans' perspective, wideout Robert Woods (foot) was taking part in practice Thursday for the first time since Week 6 and could have a chance at putting an end to his two-game absence this weekend.
