GREEN BAY, Wis. -- Rookie Kenny Clark is poised to take the next step in his young career with the Green Bay Packers.If defensive tackle Letroy Guion cant play on Sunday against Detroit because of a knee injury, Clark should be in line for much more playing time in the home opener at Lambeau Field.This could be a momentous weekend for the 20-year-old Clark, the Packers first-round draft pick from UCLA.He definitely made a big jump from Week 1 to Week 2, and he has to take another step this week, coach Mike McCarthy said.Clark filled in admirably after Guion got hurt in last weeks 17-14 loss to Minnesota. Guion and fellow defensive lineman Mike Daniels have spearheaded the Packers strong start against the run, holding opponents to a league-best 1.63 yards per carry.Last week, Minnesotas Adrian Peterson was held to 19 yards on 12 carries before leaving the game with a knee injury .Clark had two tackles and played in 66 percent of the defensive snaps, up from 12 percent the previous week against Jacksonville.Clark was slowed in training camp by a hamstring injury. Against Jacksonville, the rookie said he was filling into the game too much, or not really getting adjusted.I just needed to just come out and go, Clark said this week. I felt pretty good out there when I played Minnesota, and as the pace started going on, I felt more comfortable out there.He has a pretty good mentor lining up alongside of Daniels, a bulldozer of a lineman who is playing the best football of his five-year NFL career. Daniels consistently wins matchups in the trenches.Ive liked our aggressiveness with the guys up front. ... Its not been sit and read, theyve been attacking, defensive coordinator Dom Capers said Thursday. It comes down to lining up and whipping your man a lot of times.Its not just against the run, either.Daniels has one of the Packers six sacks this season. The pass rush has been strong, and the front seven, especially has played well.Being able to stop the run the way that we have definitely opens up the pass rush much more, Daniels said.You can see by our productivity that the run game is definitely complementing the pass rush very well.Defensive depth will be tested, though, on Sunday.Besides Guion, hybrid lineman-linebacker Datone Jones hasnt practiced so far this week because of a knee injury.Another lineman, Mike Pennel, is halfway through a four-game suspension from the NFL for violating the leagues substance-abuse policy.To help fill depth, the Packers activated defensive tackle Brian Price from the practice squad on Thursday. But expect Clark to get the first chance to line up next to Daniels if Guion cant play.You see signs of what Kenny can do. And so, those young guys have to grow up in a hurry because we need them, Capers said.OTHER INJURIESThe Packers best pass rusher, LB Clay Matthews, missed practice again because of ankle and hamstring injuries suffered in the Vikings game. S Morgan Burnett (hamstring) also sat out on Thursday. ... Starting CB Sam Shields (concussion) remains out. ... OL T.J. Lang was added to the injury report on Thursday with a hip injury.Hes got some testing to do or something. Hell be fine, offensive line coach James Campen said.ITS SPECIALS Chris Banjo and LB Jayrone Elliott, each with hamstring injuries, were full participants in practice for a second straight day. The special teams standouts missed the seasons first two games. Well, youve kind of got two core guys that know the scheme, know what were doing, have got experience, coordinator Ron Zook said.

COLORADO SPRINGS, Colo. -- Although Antonio Vargas still thinks about the cut that nearly ended his Olympic dream, his unprotected head will be clear when he steps into the ring in Rio de Janeiro.Vargas grew up sparring and competing in protective headgear, so he had never been cut in a fight before his face split open in that bloody loss at the U.S. Olympic team trials seven months ago. The gifted flyweight from Florida had to fight his way back through the challengers bracket, surviving to earn a spot on the team.Cuts havent been a major concern in Olympic boxing since 1980, but they will be a constant danger in Rio, where the 250 male fighters will box without headgear for the first time since Moscow.Fighters have had three years to adjust to the change, and theyve adapted with the same tenacity that made them boxers in the first place.Im always going to do what I have to do, Vargas said. I dont think its really changed my style. Ill still have the same style going into the Olympics. I just have to be careful.The International Boxing Association (AIBA) made a highly visible alteration to its sport when it removed the headgear ahead of the 2013 world championships. Many fighters are excited for fans to see a sport that looks more like the pros, but the move is still criticized by other fighters and coaches who believe safety has been made secondary to appearance, particularly because of the high potential for cuts in a short, multi-fight tournament.I dont think it was a good idea, taking off the headgear, because were still amateur, U.S. light flyweight Nico Hernandez said. I got cut on both eyes before. I got stitches and stuff from head-butts. I just dont think its as safe for the amateur boxers. But I also like it, because you can have more peripheral vision and you dont get as hot. Ive had a lot of fights without now, so Im used to it.The bulky protective pads were placed on Olympic fighters heads in 1984 because organizers wanted to improve safety, and theyve been pulled off the fighters heading to Rio for ostensibly the same reason.In its lengthy quest to become a professional boxing promoter with control over the Olympics , AIBA went to great lengths to establish a scientific backing for its decision to drop headgear. The IOC also cited research to support the notion that the bulky head guards reduced the number of knockouts and stoppages, thereby reducing concussions.Their conclusions have been disputed by other scientists and fighters alike, but the benefits of reemoving headgear go beyond any concussion data in an inherently dangerous sport: Quite simply, the removal of headgear allows television audiences to see the fighters faces.dddddddddddd.Billy Walsh competed in headgear for his native Ireland at the 1988 Seoul Olympics before becoming one of the amateur sports foremost teachers. The new U.S. coach has adjusted his instructions under the new rules.Without the headgear, weve now got to be a bit more mobile, a bit more flexible, a bit more careful of heads, Walsh said. Weve got to be a bit more elusive. With headgear, we just locked up. Weve had to adapt some skills and techniques, but weve adapted similar stuff we would have been teaching when they had headgear. We all have to adapt.AIBAs changes are expected to continue after Rio, too. Womens boxing kept the headgear for its second Olympic tournament because AIBA says it doesnt have enough concussion data on women, but most female fighters expect AIBA to remove their headgear next year. The male boxers are still wearing tank tops in the ring in another holdover from the sports amateur days, but those are likely to be removed soon as well.Hernandez is among dozens of top Olympians who got experience without headgear by participating in World Series of Boxing, one of two professional leagues launched by AIBA. The WSB fighters have five-round fights that largely resemble pro bouts.Even fighters who dont agree with the science of the decision credit AIBA for attempting to improve their sports marketability, and the governing body has conducted a lengthy campaign to persuade boxers to fight without the in-close, head-butting style that could ruin the tournament.Most of the American fighters also plan to turn pro shortly after the Olympics, so the absence of headgear gives them a head start on the process.But all fighters in Rio will have to be careful with the knowledge that one cut could end their Olympics.With no headgear, at first I was nervous, and I didnt really want to do it, 18-year-old U.S. middleweight Charles Conwell said. But when I got in there, it was the same, basically. You just have to worry about cuts and head-butts. Im less worried now, because Ive got more experience with it. I know the dos and donts of not having headgear on. So Im going to adjust, because I know theres going to be some dirty things that are going to happen out there. ' ' '
