New York Giants' wide receiver Plaxico Burress did not practice Friday and was listed as questionable for Sunday's game against the Dallas Cowboys. Burress has not taken part in practice for most of the season while he contends with a nagging right ankle injury he sustained in training camp. He made a rare appearance on Wednesday but did not practice on Thursday. "After any time he works he might be sore, but I don't think it will be an issue," Giants' coach Tom Coughlin said Friday. Despite the injury, Burress leads the Giants with 37 receptions and eight touchdowns this season.
