Brown (back) was listed as a non-participant on Tuesday's estimated injury report.
After missing Weeks 11 and 12 due to a knee injury, Brown continued to be listed on Texans practice reports for the next five weeks but still suited up on each occasion. He made an early departure from this past Sunday's win against the Titans with a new concern however, leaving his status cloudy ahead of the team's must-win regular-season finale Saturday at Indianapolis.
