NFL's revamped kickoff making debut in Bears-Texans Hall of Fame game

The NFL’s new kickoff rule will make its debut when the preseason opens Thursday night with the Chicago Bears facing the Houston Texans.

While both teams are expected to sit starters, all eyes will be on the overhauled kickoffs during the annual Hall of Fame game at Tom Benson Stadium.

NFL owners approved a radical change to kickoffs in order to revive a "dead play" that saw a record-low number of returns this past season.

For a standard kickoff, the ball will be kicked from the 35-yard line with the 10 kick coverage players lined up at the opposing 40, five on each side of the field.

The return team will have at least nine blockers lined up in the "set-up zone" between the 30- and 35-yard line, with at least seven of those players touching the 35. There will be up to two returners allowed inside the 20-yard line.

Only the kicker and two returners are allowed to move until the ball hits the ground or is touched by a returner inside the 20.

Any kick that reaches the end zone in the air can be returned, or the receiving team can opt for a touchback and possession at the 30-yard line. Any kick that reaches the end zone in the air and goes out of bounds or out of the end zone also will result in a touchback at the 30.

If a ball hits a returner or the ground before the end zone and goes into the end zone, a touchback will be at the 20 or the ball could be returned.

If a kick goes out of bounds before the end zone, or hits the ground or is touched by the receiving team before reaching the landing zone, the return team gets the ball at the 40.

Owners agreed to a one-year trial of the new system that was heavily influenced by the kickoffs used in the XFL spring league.

Only 21.8% of all kickoffs were returned last season as both
