TV information: A potpourri of entities are involved, including CBS and CBS Sports Network. In addition, NFL Network has a slate of 19 AAF games, beginning at 7 p.m. Sunday with Salt Lake at Arizona. Turner Sports’ B/R Live streaming site also will have games, while TNT will have one regular-season telecast and one playoff game.
Rules: Games are scheduled to last no longer than 2 hours and 30 minutes, so:
* No kickoffs. Teams will start possession after a touchdown or a half at their own 25-yard line.
* No extra points. After a touchdown, teams will attempt a 2-point conversion.
* No onside kicks. If a team is trailing by at least 17 points, it can opt to attempt converting a fourth-and-12 play from its own 28-yard line. If the conversion succeeds, the team keeps possession.
* Shorter overtimes. Each team will get the ball only once, at first-and-goal from the 10-yard line. If neither team scores, the game ends in a tie. Field goals are not allowed in the OT period.
* No TV timeouts, shorter full-screen commercial breaks, and shorter play clock (35 seconds as opposed to the NFL’s 40).
* Team timeouts will be one minute.
* No more than five defensive players are allowed to rush the quarterback on pass plays.
