Morstead spent 12 years punting for the Saints before making stops with the Jets, Falcons, Dolphins, and 49ers over the last five seasons. The 40-year-old veteran averaged 43.6 yards per punt for San Francisco last year. Current Colts punter Rigoberto Sanchez was injured during a blocked punt in the Colts’ Week 6 loss to the Titans. Morstead joins the Colts’ practice squad as insurance in case Sanchez cannot play Week 7 against the Vikings.
