DENVER (AP) - Peyton Manning figured one good Papa deserved another.

Manning's father, Archie, is joining his son as a Papa John's pitchman, spearheading the pizza chain's coin-flip promotion at the Super Bowl in the family's hometown of New Orleans.

While he was sitting out last season with his neck injury, Peyton Manning starred in a Papa John's Super Bowl commercial with Jerome Bettis. Manning was dressed up as a referee. ``Hey, a man's gotta work, OK'' he told Bettis.

After signing with the Broncos, Peyton Manning invested in 21 of the company's pizza stores in the Denver area. More recently, Papa John's approached Archie about being a spokesman for the Super Bowl promotion. Starting Sunday, fans can go online and choose heads or tails for the opening coin toss. The winners will get free pizza.
