2014 Sylvania 300

New Hampshire Motor Speedway is a 1.058-mile (1.703 km) oval speedway located in Loudon, New Hampshire which has hosted NASCAR racing annually since the early 1990s, as well as an IndyCar weekend and the oldest motorcycle race in North America, the Loudon Classic. Nicknamed "The Magic Mile", the speedway is often converted into a 1.6-mile (2.6 km) road course, which includes much of the oval.

On September 16, Ontario Country District Attorney Michael Tantillo issued a written statement stating that the findings into the investigation of the Tony Stewart incident at Canandaigua Motorsports Park on August 9 would be sent to a grand jury to determine what chargers if any will be filed against Stewart. The statement reads as follows. “Over the past several weeks, I have reviewed with members of the Ontario County Sheriff's Department their investigation, as it progressed, in the Tony Stewart matter. Recently that office concluded its work and forwarded the complete case file to me. Upon my review of all of the information contained in the entire investigation, I have made the determination that it would be appropriate to submit the evidence to a grand jury, for their determination as to what action should be taken in this matter. Accordingly, the evidence developed in the investigation will be presented to an Ontario County grand jury in the near future. “As grand jury proceedings in New York State are strictly confidential by law, I am unable to state when the matter will be scheduled, other than to state that I intend to present the matter in the near future. Similarly, because of the confidential nature of these proceedings, I cannot state who will be called as witnesses, or what any witness's expected testimony will be. When the presentation has been completed and a determination has been made, I will advise the public and the media at that time of the results.”[13]

Stewart said he would continue to cooperate in the grand jury proceeding. "I respect the time and effort spent by both the Ontario County District Attorney and the sheriff's office in investigating this tragic accident," Stewart said in a statement. "I look forward to this process being completed, and I will continue to provide my full cooperation.”[14] Stewart is expected to race this weekend and NASCAR has issued a statement allowing him to do so. "We are aware of the completed investigation and the announced next steps," NASCAR spokesman Brett Jewkes said in a statement. "First, our thoughts continue to be with all who have been impacted by this tragedy. We will monitor this process and stay in close contact with Stewart-Haas Racing. It would be inappropriate for NASCAR to comment on this case so we will continue to respect the process and authorities involved."[15]

Also on September 16, BK Racing sidelined Ryan Truex and put Travis Kvapil in the No. 83 car. This was a decision made quietly and wasn't announced till Friday, September 19. No reason was given as to why this happened and the team has not announced the immediate future beyond this weekend. “I didn't have anything going on this weekend,” Kvapil said. “We had talked about doing something with the 93. These are my guys here. I had been with them for the last two years and feel I had a hand in building this team. I don't know what the plans are beyond this weekend, but it's good to be back.”[16]

"And we didn't. But a parts failure put us down."[24] "I hate to say it, but maybe some guys get some trouble and let us back in it. Other than that, it's going to be hard for us to do it without some help."[25]
