Buffalo Bills wide receiver David Nelson, an undrafted rookie out of Florida, had been one of the team's biggest stars this summer. Today, he became the latest in a long list of injured Bills, as he was carted off the practice field Tuesday with an ankle injury. BuffaloBills.com reports that Nelson will not play any more pre-season games, and his status for the start of the season - should he make the team - is up in the air.

The 6'5", 217-pound Nelson had been so impressive in training camp that he made his NFL debut last Friday in Washington as the team's No. 4 receiver, working in with the first-team offense on a few snaps. He ended that game with five receptions, 47 yards, and his first career touchdown. Buffalo's very young and unproven at receiver, and Nelson was one of only a few players that had made a positive impression both in the camp setting and during live game action.

Nelson apparently rolled the ankle after making a catch and turning upfield, according to reports.

Fred Jackson, Marshawn Lynch, James Hardy, Ed Wang, Danny Batten and John Destin did not practice Tuesday, while Jairus Byrd and Marcus Easley were not present, according to Joe Buscaglia at WGR 550. Byrd's "complication," as Chan Gailey termed it, is considered minor, while Easley is preparing for knee surgery.
