PRINCETON, N.J. -- The Ivy League will use an experimental rule this season to move kickoffs to the 40-yard line and touchbacks to the 20-yard line in an effort to reduce concussions and further promote the safety and welfare of its student-athletes.The league announced the rule change Wednesday.The goal of the experimental rule is to limit kickoff returns, which account for 23.4 percent of concussions during games despite representing only 5.8 percent of overall plays. The Ivy League will evaluate the concussion and kickoff return data after the season.The request was made to the NCAA as a part of the Ivy Leagues overall review of concussions, which began with football in 2010 and has included eight other sports to date (mens and womens lacrosse, mens and womens ice hockey, mens and womens soccer, wrestling, rugby).It will be used only in conference games.This experimental rule change is another example of The Ivy League leading the nation in concussion prevention, Robin Harris, the leagues executive director, said in a statement. Our data showed us that kickoffs result in a disproportionate number of concussions and this rule will allow us to assess whether limiting kickoff returns will reduce the incidence of concussions.The league adopted another policy originating with the eight head football coaches to eliminate to-the-ground (live) tackling in practices during the regular season, which will also go into effect this year. Changing practice rules does not require NCAA approval.

SAN DIEGO -- Theres been a different vibe around the San Diego Padres since they called up four of their top prospects on Wednesday.One of those rookies, Carlos Asuaje, doubled for his first hit and was on base when Wil Myers hit a three-run home run in the first inning that helped the Padres beat the struggling San Francisco Giants 7-2 on Friday night.Obviously Ive been imagining getting a hit, said Asuaje, who made his big league debut Wednesday night and has started the last two games. I didnt think a double though, but yeah it was awesome, a great experience. It was kind of a relief, really.I tried to keep my wits about me as best I could, he said. I didnt want to seem all giddy in front of the guys. They already mess with me enough, so I didnt want to look too happy but man, inside it was really good.It was San Diegos seventh victory in eight games against the struggling Giants since the All-Star break.The Giants dropped into the second wild card position, a game behind the New York Mets.

He struck out five and walked five.It was great to have the offensive support and see the young guys come up and get first hits and see the excitement in the dugout, Jackson said. It was definitely a lot of fun and it makes the game fun.Busteer Posey pulled the Giants to 3-2 with a two-run double off the wall in left-center with one out in the fifth.ddddddddddddIm just trying to bounce back, Jackson said. I wish I could have less walks. They kind of cost me in the fifth inning, walked a couple then Posey comes up and got a big hit, but nevertheless, all in all, some decent game of bounce back. Were always hard on ourselves.Giants reliever Matt Reynolds came on to start the bottom of the fifth and allowed four runs without getting an out. He walked in a run and was chased by Alex Dickersons two-run single to right. George Kontos came on and got the first out before Austin Hedges hit a sacrifice fly to make it 7-2.Suarez allowed three runs and five hits in four innings, struck out one and walked one.TRAINERS ROOMGiants: RHP Johnny Cueto, who left his start Tuesday night with a strained groin, was scheduled to play catch before the game.
