INDYCAR: Busch rules out Indy 500 return for 2016

Kurt Busch has ruled himself out of this year's Indianapolis 500.

The 2004 Cup champion, who finished a remarkable sixth for Andretti Autosport on his Indy debut in 2014, issued a statement on Wednesday confirming that a return to IMS for the 100th running of the Indy 500 is off the table.

"After seriously contemplating making another run at 'The Double,' and in response to the many questions I receive on the subject as the Month of May approaches, I wanted to state that I will not be participating in this year's 100th running of the Indianapolis 500," Busch said.

"I must say this was not an easy decision and it does not in any way reflect upon my desire to compete again in one of the world's greatest races; it is based solely on a need to maintain the focus and momentum we have built early in this NASCAR season with our #41 Stewart-Haas Racing, Haas Automation/Monster Energy Chevy team – hopefully all the way to Homestead and the championship weekend.

"My experience with Andretti Autosport and its drivers was so very positive and the way in which the IndyCar fans and media welcomed me, it is undoubtedly one of the highlights of my career both personally and professionally. Fortunately, Michael [Andetti] and the Indianapolis Motor Speedway have left the door open for a future run, and perhaps one day I will take them up on that, it just won't be this year."

Busch fell short in his attempt to complete the Indy/Charlotte double two years ago when he dropped out of the Cup race with a blown engine after 220 laps. His five Cup starts this year have yielded four top 10 finishes, with a current season-best of fourth at Atlanta.
