On days two through five of preseason training camp, no live contact shall be permitted. Players may be on the field no more than 3.5 hours. Two on-field sessions are permitted as follows: one session may be a full speed practice, which can be no longer than 2.0 hours. This session may include all customary practice activities at the head coach’s discretion. The other session on the same day may be for a maximum of the remaining 3.5-hour on-field time, and is limited to only walk-through instruction and drills and plays conducted at an acceptable walkthrough pace (i.e., Pro Bowl practice pace), as demonstrated in a video jointly approved by the parties, with offensive players lining up across from defensive players, or kicking team players lining up across from return team players. No helmets may be worn during the second practice. The two on-field practices may be conducted in either order.
