UNDATED (AP) — The NFL is making extra points a bit more challenging.

League owners have approved the competition committee's proposal to snap the ball from the 15-yard line on extra-point kicks. In recent seasons, kickers made more than 99 percent of the kicks with the ball snapped from the 2.

That proposal also keeps the 2-point conversion at the 2 and allows the defense to return a turnover to the other end zone for the two points, similar to the college rule.

The league announced the changes at the owner's meeting in San Francisco. Before the meeting, New England Patriots owner Robert Kraft said he will not appeal the penalties for the team's role in the use of deflated footballs in the AFC championship game. Commissioner Roger Goodell fined the Patriots $1 million and took away two draft choices, including a first rounder next year.

Kraft says he was putting the league before his franchise because the agenda of one team should not override the good of all 32.

Kraft's decision will not affect quarterback Tom Brady's appeal of his four game suspension in the case.

Meanwhile, the players' union has asked Goodell to recuse himself from the appeal hearing for Brady. The union calls Goodell a "central witness in the appeal hearing," adding he is not impartial. The NFLPA is seeking a neutral party to serve as an arbitrator.

The union also has asked a federal court to hold the NFL and Goodell in contempt in the Adrian Peterson case.

The NFL Players Association says that Goodell and the league "have deliberately ignored both the court's decision from 11 weeks ago" and the NFLPA's repeated requests to comply with that order.

The NFL was ordered in late February to change its decision to suspend the Minnesota running back indefinitely after he injured his 4-year-old son with a wooden switch last year in an attempt to apply discipline. He missed all but one game while on the commissioner's exempt list.

Peterson's suspension was lifted last month by Goodell, but the running back has not joined the Vikings.
