Collins (calf) remained sidelined at Thursday's practice, DJ Bien-Aime of ESPN.com reports.
Collins didn't practice Wednesday, either, making Friday's practice a pivotal one when it comes to determining his status for Sunday's game against the Titans. Per Aaron Wilson of KPRC 2 Houston, Collins is making progress in his recovery from the calf strain he suffered in this past Sunday's loss to the Jets, but his injury is considered similar to the one that he sustained Week 9 at Tampa Bay. Collins ended up missing the Texans' Week 10 win over the Bengals and could be in line for another one-game absence this time around.
