Some around the NFL raised their eyebrows when Terrell Owens practiced with the Seahawks on Wednesday. "Players have a 3-day acclimation period during the preseason," league spokesman Greg Aiello said when questioned by Fort Worth Star-Telegram beat writer Clarence Hill. "Day 1 is for the physical and meetings. Day 2 and 3 the player may participate, but only in helmet and shells or a padded shirt. Day 4 and for the rest of camp is in full pads. The Cowboys are doing it correctly. Don't know about Seattle." Owens signed with Seattle on Monday and was on the field two days later. Aiello later said that the NFL was gathering facts about Owens' practice.
