The Texans re-signed WR David Anderson to fill a void at wideout with Kevin Walter nursing a shoulder injury.
Anderson, who was cut by Houston before camp and failed to make the Broncos' 53-man roster, has played in five seasons with the Texans. In 12 games last year, he had 11 catches for 117 yards.
Walter suffered a badly bruised shoulder in Sunday's season-opening win. Anderson joins WRs Jacoby Jones and Bryant Johnson behind star WR Andre Johnson.
