Collins (calf), who is officially listed as questionable, isn't expected to play Sunday against the Titans, Adam Schefter of ESPN reports.
Collins was unable to practice in any capacity throughout the week but still is considered questionable. If he is forced to sit out, wideouts Noah Brown (knee), Robert Woods and John Metchie and tight end Dalton Schultz would likely represent the top pass catchers for quarterback Case Keenum. Collins' status will become official when Houston releases its inactive list 90 minutes prior to Sunday's 1 p.m. ET kickoff.
