WATKINS GLEN, NY - Dale Earnhardt Jr. made his first appearance at a racetrack since being diagnosed with a concussion four weeks ago, and he has a message for his fans:Hes not retiring. Not yet, anyway.Earnhardt, who has missed the last three NASCAR Sprint Cup Series races and will miss at least two more, took questions for 30 minutes during a media appearance at Watkins Glen International, where the Cup Series races on Sunday.The popular driver said he is continuing to make progress in his therapy, but as long as he continues to suffer from ocular imbalance issues, there can be no set timetable for his return to the seat of the No. 88 Chevrolet.However, he does plan to return to competition as soon as he is cleared by doctors.Im not ready to stop racing; Im not ready to quit, Earnhardt said.Its a slow process and I wish it wasnt, he continued. I dont know how long its gonna take, and as impatient as I am, I worry about everyone elses patience as well.But Im not going to go in the car until the doctors say Im ready to race.Earnhardt sustained the concussion in a relatively minor looking crash at Michigan Speedway on June 12, but he said the symptoms were slow to develop. He drove in three more races before recognizing that he wasnt feeling right, at which point he sought medical attention.Unfortunately its a slow process and theres no guidelines or rulebook, he said. Theres no consistent history over how long this really takes to clear up so were just having to be patient.My doctors feel great about the opportunity that I not only will be healthy again, but they can actually make my brain stronger to be able to withstand these common events, he added. The event that I had a Michigan which they tied this concussion to, I should have been able to get through that without having a concussion. So theyre working not only to get me healed up, but to make sure I can compete and I can go through events like that without any concern.Earnhardt has been involved in several major accidents over the course of his 16-year NASCAR career, and he missed two races due to a concussion in 2012.He said his therapy is different this time, with doctors encouraging him to engage in activities outside his comfort zone. That includes things like dining out, playing with his sisters kids, or making himself available to the media at Watkins Glen.In this situation, my doctor says its good therapy to go somewhere that makes you feel worse, Earnhardt explained. He wants me to do anything that pushes me into areas to get my anxiety and drive the symptoms so my body gets used to them. He calls that exposure, and this [press conference] is probably the worst situation as far as making my senses to go haywire.I just want to get better, he added. Nothing else is really a priority except for just getting the symptoms to clear up and get back to feeling like yourself. Thats all that Im thinking about. Its a challenge, but weve got some great doctors and I really believe and trust what they are telling me. I just have to do what they tell me. Steven Matz Jersey .

Talk of?Colin Kaepernicks?decision to sit down during the national anthem reached far beyond football Monday.And many werent thrilled with the?San Francisco 49ers?quarterbacks strong words about why he is doing it: to instigate change and challenge authority when it comes to race relations and what he considers police brutality.Martin Halloran, the San Francisco Police Officers Association president, sent a letter Monday to NFL commissioner Roger Goodell and 49ers CEO Jed York denouncing Kaepernicks ill-advised statements and a naivete and total lack of sensitivity toward police, along with an incredible lack of knowledge about officer-involved shootings.The police union invited Kaepernick or anyone else from the league to visit the San Francisco police academy to build communication and understanding about the profession.I only wish Mr. Kaepernick could see the emotional and psychological challenges that our officers face following a fatal encounter, Halloran wrote. Some are so affected they never return to the streets. In short, Mr. Kaepernick has embaarrassed himself, the 49er organization, and the NFL based on a false narrative and misinformation that lacks any factual basis.ddddddddddddKaepernick, who has sat through the anthem at all three 49ers preseason games so far, is prepared to keep fighting for what he believes in, even alone.The fact that it has blown up like this, I think its a good thing. It brings awareness, Kaepernick said Sunday. Now, I think people are really talking about it. Having conversations about how to make change. Whats really going on in this country. And we can move forward. ...There is police brutality. People of color have been targeted by police. So thats a large part of it and theyre government officials. They are put in place by the government. So thats something that this country has to change. Theres things we can do to hold them more accountable. Make those standards higher.Information from The Associated Press was used in this report. ' ' '
