Whereas teams used to be required to report to training camp 15 days before their preseason opener, 30 NFL teams now must report July 28, which is 47 or 48 days before Week 1 of the regular season, league sources said.
The 26 teams playing Sunday, Sept. 13, must report to camp 47 days before their opener, and the four teams scheduled to play Monday, Sept. 14, must report 48 days before that game. The Kansas City Chiefs and Houston Texans, who are scheduled to kick off the season on Thursday, Sept. 10, are required to report to camp the same 47 days in advance of the opener, which would be July 25.
