TALLADEGA, Ala. – David Ragan says he has "unfinished business."

Ragan will move to his third Sprint Cup team this season – Michael Waltrip Racing -- next week for the Kansas Speedway race. He will remain in the No. 55 Toyota for the remainder of the season.

Sunday's GEICO 500 at Talladega Superspeedway will mark his last ride as a substitute driver for injured Kyle Busch.

Ragan started the season with Front Row Motorsports but jumped at the chance to replace Busch in the potent Joe Gibbs Racing Toyotas.

It was clear that the JGR ride was temporary, however, as Busch is expected to return soon from a broken leg and foot suffered in a crash in the Xfinity Series opener at Daytona International Speedway on Feb. 21. Rookie Erik Jones will drive for Busch next week at Kansas. The team has not provided a schedule for the No. 18 beyond that.

Ragan will be in the No. 55 MWR Toyotas vacated by Brian Vickers, who continues to battle health issues related to blood clots.

"It's much more important for me to have an opportunity going forward with a full-time car and a very competitive organization like Michael Waltrip Racing than it would be for me to run a few more races before Kyle's return," Ragan said Friday. "Ultimately, I knew this (the JGR situation) would be just a three-month or so deal. For me, the big picture is the entire season and having a shot to make the Chase."

Although he is winless, Ragan sits 19th in the driver standings. He'll try to improve on that and take a shot at scoring a Chase-qualifying race win as he rides with MWR the rest of the season.

"It's been a little weird, for sure, just trying to understand the systems each of these teams has in place," Ragan said. "We were working so hard to find financial backing and make the 34 (car at Front Row) a full-time car this year. Then the Joe Gibbs thing happened. I had just this weekend finally gotten everyone's name down, and now that process starts all over again."
