DOVER, Del. - Four-time NASCAR champion Jeff Gordon said Friday he will have to retire if he continues to suffer the same, excruciating back pain that he did before last weekends Coca-Cola 600. The 42-year-old Gordon is in no hurry to slow down. But he said he hopes he has found some solutions to the back woes that nearly forced him out of NASCARs longest race. Gordon cut short his practice runs last week because of back spasms and there was some concern whether or not he would be able to race. Regan Smith was on standby and Gordon needed treatment after the practice session. But he wound up in his familiar seat behind the wheel of the No. 24 and finished seventh, his ninth top-10 finish in 12 races this season. Gordon knows consistent, shooting pain like he suffered at Charlotte Motor Speedway could drive him toward an early retirement. "I can tell you, if that happens many more times, I wont have a choice," Gordon said Friday at Dover Motor Speedway. Gordon had soreness Monday and Tuesday, though that didnt deviate too much from how he would feel after driving 600 grueling miles. He said his back is not at 100 per cent, and probably never will be behind the wheel. At Daytona this year, Gordon insisted he was serious about considering retirement should he win a fifth championship. He looks every bit a title contender — he has a win and holds the points lead — and gutting out Charlotte proved to his Hendrick Motorsports team "its going to take a lot to get us down." Gordon suffered serious issues years ago in his back, specifically his lower spine, and needed anti-inflammatory medication and workouts with a trainer to return to full strength. He drove in pain during a winless 2008 season and briefly contemplated retirement. For all his back woes, Gordon said he never felt the stabbing pain there like he did last weekend. Gordon said hell make adjustments to his race weekend routine to keep his back loose to withstand hours crunched in a stock car. He needs to stay active and not sit during lengthy breaks in practice and qualifying. Gordon sat more than three hours last week between practice and qualifying, a gap that left he believed led his creaky back to a breakdown. "Once that happened, there was nothing that was going to fix it until I had those injections on Saturday," he said. Gordon has no standby driver at Dover. He felt fine on Friday. But once inside the No. 24, all bets are off. "Its just something I continue to learn and push through," he said. "Its no big deal."

At least 22 people were reported injured. There was not yet any word on whether foreign tourists were among those killed or injured. Brazilian officials didnt think the casualty numbers would rise too sharply -- though they said they had not yet reached a small passenger car that was flattened by the falling overpass. It was not known if anyone inside the car escaped or remained inside. The incident is the biggest black eye yet for Brazils hosting of the World Cup, which has been carried out with less chaos than many had feared. In the run-up to the event, there were serious concerns about the ability of Brazils airports and roads to handle the influx of tourists because of delays or outright cancellations of projects to improve urban transportation. After Brazil was awarded the World Cup in 2007, politicians promised $8 billion would be spent on 56 airports, subway lines and other such projects nationwide. But less than 10 of the infrastructure projects were completed in time for the tournament, including the project where the overpass collapsed in Belo Horizonte. It was not known what caused the overpass to fall. Cowan, the construction company responsible for building it, said investigators were on site but had not released any conclusions. "It sounded like an earthquake or a bomb," said Alexandra Pereira, a teacher who was taking a nap with her 10-year-old son in her apartment building jjust 20 metres (yards) from the overpass.dddddddddddd"I looked out my window and panicked. I couldnt see anything but a huge cloud of dust." Within seconds, Pereira said, her neighbours from the ground floor rushes out to pull injured from the bus that was partially trapped under the overpass. Pereira said she and several neighbours in a group of nine residential buildings close to the overpass had long complained to the mayors office that they feared for their safety from the construction and asked authorities for compensation so they could move. She said the request was rejected and the mayors office assured them the project was safe. The mayors office ws closed for the day, but Lt. Col. Edgar Estevo da Silva, a spokesman for the fire department, said officials had inspected the nearby apartment buildings and didnt find any sign they were at risk because of the overpass collapse. Among the dead was a woman who was driving a commuter bus trapped by the overpass died, said Capt. Federico Pascual of the Belo Horizonte fire department. An official in the mayors office reported the death of a second person. The official said 22 people were known to be injured. The official spoke on condition of anonymity because he wasnt authorized to talk to the media about the incident. The overpass collapsed about 3 miles (5 kilometres) from Mineirao stadium, which has hosted several World Cup matches in recent weeks and is the site of a semifinal match Tuesday. The overpass "arched over a really busy thoroughfare," Pascual said. Security camera footage showed heavy traffic on the street below the structure the moment that the overpass collapsed, striking vehicles below and trapping them underneath.
