BOCA RATON, Fla. (AP) NFL owners have approved as a one-year trial ejecting a player who draws two unsportsmanlike conduct penalties from specific categories.

Those categories include throwing a punch at or kicking an opponent; taunting; and using abusive, threatening or insulting language or gestures.

Also approved Wednesday as a one-year trial was placing the ball at the 25-yard line after touchbacks on kickoffs instead of the 20. The league is seeking ways to reduce injuries on kickoff returns, which it says statistically are the most dangerous plays in the game.
