NASCAR XFINITY Series points leader Elliott Sadler is staying put next year and so his long-time primary sponsor, OneMain.

Wednesday morning, JR Motorsports announced that consumer finance company OneMain has signed a multi-year extension to continue sponsoring Sadler and the No. 1 JR Motorsports race team owned by Dale Earnhardt Jr. and his sister Kelley Earnhardt Miller.

Next year JR Motorsports will campaign full-time cars for Sadler, Justin Allgaier and William Byron, and enter a fourth car in select events.

OneMain will be Sadler's primary sponsor for 20 races in 2017. Next year will be the seventh season for the OneMain-Sadler relationship.

"We are thrilled to continue our partnership with Elliott Sadler and JR Motorsports," said OneMain Executive Vice President and Chief Operating Officer Bob Hurzeler. "... Elliott has been an outstanding ambassador for OneMain and we look forward to our continued success with Elliott and JRM, on and off the track."

"Elliott and OneMain are integral pieces to the make-up of our company," said Earnhardt Miller, the team's general manager. "Elliott's talent speaks for itself, but what's more, his experience and leadership is completely necessary for our younger guys. He brings a professionalism and charisma that permeates our entire organization, and I think he brings it to OneMain as well. I'm glad they have decided to come back with their sponsorship. We've got many things to accomplish together."

This year Sadler has one victory seven top fives, and a series-leading 19 top-10 finishes in 22 starts. For his career, Sadler has 15 NASCAR's touring series race wins.

He has been an NXS regular since 2011, twice producing runner-up finishes in the championship point standings (2011-12).

I'm very humbled, ecstatic, and thankful for the news coming out today.. Thank you @OneMainRacing @JRMotorsports 👍 https://t.co/niHjUD7qS6
