Former NFL offensive tacke Rob Pettiti auditioned for the Buffalo Bills on Tuesday, according to a league source.
He wasn't immediately signed, though.
The Bills could use some depth along the offensive line with their proliferance of injuries.
Petitti played for the Florida Tuskers in the UFL this season.
A former Dallas Cowboys seventh-round pick in the 2005 NFL draft, Petitti started every game as a rookie.
He also has previous stints with the New Orleans Saints and the St. Louis Rams.
