Colts' Joseph Addai staying behind

INDIANAPOLIS -- Three Colts players will not travel to Cincinnati for Sunday's game.

Running back Joseph Addai, left tackle Anthony Castonzo and defensive tackle Drake Nevis will stay in Indianapolis, the team says.

Addai left last week's game in the first quarter after hurting his hamstring. Castonzo missed last week's game with a sprained ankle. Nevis has been battling a back injury.

When Addai went out last week, rookie Delone Carter got more playing time. Indy could also use Donald Brown, their first-round pick in 2009, more.

The Colts also have announced that Tom Zupancic, senior vice president of sales and marketing, has retired. Zupancic first joined Indy as a part-time strength coach in 1984.
