The NFL will experiment with a potential rule change involving extra points in the first two weeks of the preseason. The ball will be moved from the 2-yard line to the 15-yard line, making an extra point the equivalent of a 33-yard field goal.

Ravens Pro Bowl kicker Justin Tucker said he’s interested to see how the change works out but made it clear that he’s not a fan of adding to the length of extra points.

“I don’t think it’s really going to change anything that we do aside from just practicing, just the visual of seeing an extra point from a little further back,” Tucker said. “It is what it is. If there is a rule change, we’ll adapt and overcome, but I don’t think the game needs to be changed unless there’s a real safety concern. I think people are proposing some of these rule changes just because maybe they don’t have anything better to do. … As long as there’s not a safety concern on a particular phase of the game, then I don’t think there’s a reason to change it.”

Tucker is 68-for-68 on extra points in his NFL career and said he hasn’t missed one since he was a junior in high school.

Ravens coach John Harbaugh said rookie defensive tackle Timmy Jernigan, who is dealing with back spasms, has assured him that he’ll play in the Ravens’ preseason opener Thursday against the San Francisco 49ers, but team doctors will need to clear him first. … The Ravens had rookie first-round draft pick C.J. Mosley as their starting weak-side inside linebacker on their initial depth chart. Haloti Ngata was listed as the starting defensive tackle at Arthur Jones' vacated three-technique spot. Brandon Williams is starting at nose tackle, where Ngata primarily lined up last season. … Ngata was working on his snapping during practice. He could be an emergency option if long snapper Morgan Cox gets hurt during a game.
