Dunn has been waived by the Texans.
Dunn recorded three combined tackles in two games played for the Texans this season.
Dunn was promoted to the Texans' active roster from their practice squad on Wednesday, Aaron Wilson of the Houston Chronicle reports.
Dunn had jumped from the practice squad to the active roster and back down again earlier this season, while he has yet to make an impact defensively. He'll look to secure his roster spot for a longer period of time as he provides depth behind Vince Wilfork and D.J. Reader at nose tackle.
Dunn was waived by the Texans on Thursday.
His spot on the roster will be taken by cornerback Robert Nelson, who was activated from the practice squad.
