A track guy in college, Hannon was claimed off waivers from the San Francisco 49ers, who released him this week with the idea of re-signing them to their practice squad.
Hannon took the roster spot created when guard Justin Smiley was placed on injured reserve.
As for Carpenter, he was named Wednesday as the AFC Special Teams Player of the Month for November.
During that time, Carpenter was 8-for-8 on field goals, including five from 40 yards or more. Another kick was the game-winner against Oakland in the final minute.
Carpenter became the second player in franchise history to be named AFC Special Teams Player of the Month; Olindo Mare was honored for his performance in October of 1999.
