Cowboys wide receiver Patrick Crayton will not be in attendance when the team begins their organized activities on Monday. Fred Lyles, Crayton's agent, said his client will miss the three days of voluntary workouts this week but plans on attending future OTAs and mandatory minicamps. "The Cowboys organization was notified on Wednesday that Patrick will not attend voluntary workouts," Lyles said. "Patrick is excited and preparing himself for the 2010 season. We are confident that the uncertainties regarding his immediate future with the organization will be resolved in time." Crayton requested a trade when Dallas drafted Dez Bryant in the first round of last month's NFL Draft.
