Bills add two to offensive line audition

BY NICK ST. DENIS

The Buffalo Bills are currently auditioning for roles on their offensive line, and the team upped the competition Sunday.

A couple hours before taking the field for their first training camp practice of 2013, the Bills announced the signings of Antoine Caldwell and Tony Hills, most recently of the Houston Texans and Indianapolis Colts, respectively.

According to the team's website, Caldwell, who has 40 games and 19 starts under his belt, is expected to compete with Doug Legursky and Colin Brown for the starting left guard job. Caldwell was drafted in the third round in 2009.
