EAST RUTHERFORD, N.J. (AP) - The New York Giants have signed former Denver Broncos defensive end Robert Ayers. Ayers' addition Wednesday makes him the 13th veteran the team has signed since free agency started. Ayers had a career-high 5.5 sacks last season for the AFC champion Broncos. A former first-round draft choice and a New Jersey native, he is the fourth participant from February's Super Bowl, and the third from the Broncos, to join the Giants. The others are cornerback Dominique Rodgers-Cromartie and return specialist Trindon Holliday. Cornerback Walter Thurmond left Seattle to join the Giants. The Giants lost defensive captain Justin Tuck to Oakland in free agency, leaving Jason Pierre-Paul, Mathias Kiwanuka and second-year pro Damontre Moore. Pierre-Paul was limited by injuries last season.
