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." . -- Isaiah Pead took a stutter step forward, then raced to the left sideline and travelled 60 yards up the field before finally getting tripped up by a leg tackle. .
