The Texans promoted cornerback Cornell Armstrong from their practice squad Saturday, according to Armstrong’s agent, Brett Tessler.
Houston originally signed him Sept. 1 but waived him nine days later.
He then signed back to the Texans’ practice squad.
Miami made Armstrong a sixth-round choice in 2018.
He played 15 games last season. Armstrong played 83 snaps on defense and 268 on special teams as a rookie.
He has not played for Houston this year.
