ORCHARD PARK, N.Y. (AP) - Receiver David Nelson is preparing to become a free agent after the Buffalo Bills informed the third-year player they will not extend him a contract offer to retain his rights.

General manager Buddy Nix says he informed Nelson's agent of the decision Sunday. The Bills reached a similar decision with receiver Donald Jones earlier this month.

The move wasn't entirely a surprise for Nelson, who anticipated the possibility after the Bills fired coach Chan Gailey. Doug Marrone was hired to take over last month.

An undrafted free agent out of Florida, Nelson was a dependable contributor during his first two years, with a combined 92 catches for 1,011 yards and eight touchdowns. Last year, he never made it past the season opener, when he tore a right knee ligament.
