Fairbairn (quadriceps) didn't practice Wednesday, DJ Bien-Aime of ESPN.com reports.
Fairbairn wasn't able to finish out Sunday's win over Tampa Bay and now is expected to miss multiple weeks. Though the Texans haven't officially ruled Fairbairn out for this Sunday's game at Cincinnati, he doesn't appear likely to practice this week. The Texans signed Matt Ammendola to their practice squad earlier this week, presumably with the intent to elevate him Sunday to handle kicking duties in Fairbairn's stead.
