"I've thought about this decision for many months, if not longer", the 38-year-old said.
Kahne's departure opens the door for Leavine Family Racing to make a change or potentially go younger next season. Sadler, along with his brother Hermie, have had a lasting impact in motorsports in Virginia from racing go-karts at age seven to his 1995 track championship at South Boston Speedway to competing full-time in the Monster Energy NASCAR Cup Series and NASCAR Xfinity Series (NXS). He's been racing full-time in either the Xfinity Series or the Cup Series since 1997. Sadler's best race in the Monster Energy Series at Richmond was a seventh place finish in the Chevy American Revolution 400 on May 14, 2005. Since then, he racked up 18 career wins in the Cup Series. He's been the series runner-up an astounding four times, including in both 2016 and 2017, and never finished worth than sixth in the final standings.
"I'm not sure what the future holds for me", Kahne said. "I need to spend more time doing the things I enjoy and love and that's spending time with (son) Tanner and my sprint auto teams". We still have some work to do this year in the #95 and I look forward to finishing the season with this team.More news: Trump wants to replace quarterly SEC filings with half-yearly reports

"Thanks to everyone that believed in this kid from Enumclaw, Washington".
Kahne is now 28th in the Cup Series standings and would need to win one of the final three regular season races to qualify for the 16-driver, 10-race playoffs this fall.
To date, the veteran driver has started in more than 800 races in NASCAR's top-three national series. A total of 20 races in the Camping World Truck Series rounds out his experience in each rung of NASCAR's three nationwide leagues.
