Eagles defensive back Asante Samuel and right tackle Winston Justice will not play in Sunday's game at Dallas.
Neither Samuel nor Justice traveled to Dallas today. Both players have knee injuries.
Joselio Hanson will start in Samuel's place, with King Dunlap playing in Justice's spot.
"Mentally, you've got to prepare yourself like you're going to start, because you don't want any surprises on game day, you don't want to feel like you're thrown into the fire," Hanson said Friday before a determination about Samuel had been made. "But I've taken the reps all week and I feel comfortable."
