Could New Hampshire be the last race for Jeff Burton?

Toyota post-qualifying notes & quotes from New Hampshire Motor Speedway, #66-Jeff Burton’s comments:
Q) How was qualifying?
Burton‚ ‘We were really disappointed. All day we’ve been way off in qualifying trim. We had a great test here. We made one qualifying run here at the test and it wasn’t very good ‘” I didn’t think it was very good. Honestly, that’s about what we ran right there. I’m pretty optimistic about the race. Today, in qualifying trim we just weren’t in the ball game. Disappointed, but tomorrow’s another day.’
Q) Is this your final race?
Burton‚ ‘I can give you a positive that I don’t k now. I think it’s a good chance. I’m okay with that. I’m really comfortable with what I’m doing. It’s fun being here. I have a lot of friends here. I’ve been going to quite a few races this year. If this is my last race, it’s cool with me for it to be here. This isn’t my home track, but this is certainly a track a lot of my career has been shaped at this race track.’(Toyota Racing transcript)(7-12-2014)
