FORT WORTH, Texas — Denny Hamlin can put off until after the season the surgery he needs to repair a torn labrum in his left shoulder that has bothered him for some time.

There is still the push to try to win his first NASCAR Cup championship, and a lingering feud with Joey Logano.

A week after another confrontation between the title contenders, Hamlin and Logano got to Texas with two races left to try to stay in the top four spots for the season finale at Homestead.

Hamlin said Friday that he doesn’t know what caused the injury, but that it hasn’t affected him while driving the No. 11 Toyota for Joe Gibbs Racing. And it wasn’t aggravated when he got horse-collared and pulled to the ground by a member of Logano’s crew in a wild scuffle after the race at Martinsville Speedway in Virginia last weekend.

“It’s something that’s been nagging really for years,” said Hamlin, who turns 39 this month. “It just got to the point where it was really bad, got it scanned and figured out what it was.”

Dave Nichols Jr., the tire technician for Logano’s crew who dragged Hamlin to the ground, was suspended by NASCAR and will miss Sunday’s race in Texas. With crew members around them, the drivers were having a discussion about an on-track incident that suddenly flared into a chaotic confrontation.

“I thought that my guys were pretty level to be honest with you through that whole deal. I think you could see quite a few times Joey is right in front of them and no one lays a hand on Joey,” said Hamlin, adding that he felt Logano’s crew chief, Todd Gordon, lacked control of his team.

Logano countered that Gordon does a great job leading the No. 22 Team Penske car, and chuckled about Hamlin’s response when the Gibbs driver was asked if he ever got the feeling Logano knows that he can get to him.

“No, he’s not that smart,” Hamlin said.

Hamlin, a 15-season Cup Series veteran, is second in the standings with two races remaining to qualify for the title-deciding finale, with Logano fourth. Hamlin has won at Texas three times, including the spring race seven months ago.

After the pending surgery, Hamlin said he will be ready for the 2020 season-opening Daytona 500. He said the recovery time will be 10 weeks; qualifying at Daytona is Feb. 9, which is 12 weeks after Nov. 17 finale at Homestead.

Hamlin said the torn labrum, which is cartilage in the ball and socket joint of the shoulder, was progressively feeling worse late in the summer until he got a cortisone shot several weeks ago.

“That’s like my saving grace when this thing started hurting, so that really changed. It went from being immobile to feels like there’s nothing wrong with it,” Hamlin said. “Doctors came a gave me a little bit of relief with that just to kind of get me into the offseason part of things.”
