BRISTOL, Tenn. -- NASCAR fans dont need a reason to pay extra attention when Kyle Busch and Brad Keselowski race for position at any track. The two rivals are far from friends.So it was of little surprise that they didnt have the same view of their incident with four laps left in the Xfinity Series Food City 300 Friday night at Bristol Motor Speedway.Busch attempted to pass Keselowski for the lead by using the inside lane, and when Busch tried to come up in front of him in the upper lane, Keselowski clipped him in the right rear. Buschs car slapped the fence and then got plowed into from behind by Ty Dillon.As he left his hauler, Busch was asked if he thought that incident was clean, and he replied: Hes a dirty racer.Keselowski said while he didnt want to see it end that way, there just wasnt enough room and he had position in the lane. He said Busch had no choice to slide up because the inside lane wasnt as good in Turns 3 and 4 as it was in Turns 1 and 2, where Busch initially had made the move to pass.We race each other hard, Keselowski said. Thats what racing is all about. He would have done the same thing if he was in my shoes, Im 100 percent certain. I guess were both dirty racers, then, by that definition.The two drivers have traded barbs before, including at Bristol in 2010 when they had contact on the track. There would be little surprise if they battled for spots again in the Sprint Cup race Saturday night.Everybody loves hard racing until they are a part of it and it is their driver that doesnt come out on the good end, Keselowski said.Keselowski ended up losing the lead when he ran out of gas with four laps left in the race, which was extended by eight laps for cleanup after the Busch wreck. Austin Dillon won the race. Keselowski ended up 12th, and Busch was 24th.

Randy Jones Padres Jersey . PETERSBURG, Fla. OWINGS MILLS, Md. -- The Baltimore Ravens fielded the same offensive line in their first three games. They won all of them.Then injuries started happening, and the rapport the quintet established was no longer viable. Not entirely by coincidence, Baltimore lost four in a row to fall below .500.Although the Ravens (5-4) have won two straight to take over first place in the AFC North, the shuffling of their offensive line remains a steady constant. After losing rookie guard Alex Lewis to a high ankle sprain, Baltimore will field a different offensive line for the eighth time in eight games Sunday in Dallas.Not ideal, coach John Harbaugh said Wednesday. Youd like to have continuity with your offensive line -- working together on those combination blocks, the calls, being on the same page.Center Jeremy Zuttah is the only player on the line to play the same position in all nine games. Five-time Pro Bowl right guard Marshal Yanda has missed three of the last four games with a shoulder injury; top draft pick Ronnie Stanley (foot) missed four straight starts at left tackle; and now Lewis will be lost for at least six weeks after being hurt in last Thursday nights 28-7 win over Cleveland.Its a wonder quarterback Joe Flacco can still walk after operating behind a makeshift front thats yielded 20 sacks and created precious few holes for the leagues 28th-ranked rushing attack.Anytime you have moving parts on a team it takes a lot of work together to get it right, Flacco said. But the guys in there are fighting, and thats all you ask for. It hasnt been perfect, and weve got to get better. Ive got to be better at dealing with some things.At the end of the day, were probably going to have to learn to live with one or two miistakes a game and expect to be good enough at the little things to overcome them.dddddddddddd Thats just where we are right now.Yanda participated in practice Wednesday and could return to face the Cowboys (8-1). Before his recent absence he played in 53 consecutive games.If you keep the same five guys for a long time, thats a real good thing. But the reality is that injuries happen, Yanda said. Were just trying to put the best five guys out there week to week. That changes sometimes.This year, its happened a lot.Youve just got to roll with the punches and do your job no matter what happens. Thats just the sport, Stanley said. Its definitely easier to have someone youve been playing with because you build chemistry over a period of time. But people are going to get hurt, and you have to be ready for it.For the Ravens, its next man up -- at just about any time and on any place on the line.If you had your way, youd have the same five guys out there, right tackle James Hurst said. But weve got a really good group thats willing to put in the extra time to make it work.In addition to playing special teams, Ryan Jensen has started twice at right guard and at left guard this season. He also stepped in last month after right tackle Rick Wagner was injured.Since Ive been here we havent had issues like this with injuries and stuff like that, said Jensen, now in his third year with Baltimore. But weve found a way to figure it out and get it tuned up. Weve got a two-game winning streak, so were getting there.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFL ' ' '
